[edit] Bridged modem
[edit] Introduction
In this case the router itself creates the PPPoE connection to the ISP server; but to work, the connection between the modem and the router must have an IP address. Usually the modem gives an address to the client; but this address will never be used except to access the configuration interface of the modem.
My modem is a Speedtouch 510, is IP address is 10.0.0.138 and it gives the 10.0.0.1 address to the device connected to it. The easiest way to know these addresses is to connect the modem directly to your computer and take a look at your network card configuration. The default gateway is the Modem address and the Card address is the one provided by the modem.
Note: Many modems come configured to use the 192.168.1.x subnet. This is the same subnet that DD-WRT uses for the LAN by default. You need to either set the modem to use a different subnet or set the router's LAN to use an IP in a different subnet such as 192.168.2.1 so that they're not using the same subnet.
So it looks like this.
By default if you type the IP address of the modem you have an 'Impossible to contact the server' error.
[edit] Primary Method
Replace the 10.0.0.2 with an IP in the same range as the modem. If your modem is 10.0.0.1, you should use 10.0.0.2. If your modem is 192.168.0.1, use 192.168.0.2
On builds newer than 42755 you may need to change the above code and enter both lines under the firewall settings instead of splitting them:
and click on [Save Firewall]
On older builds the below was the original code to use:
- Go to Administration -> Commands
- Enter
and click on [Save Startup]
and click on [Save Firewall]
Notes:
- `nvram get wan_ifname` gets the WAN port of your router automatically. If you wish to enter it manually, you should run echo `nvram get wan_ifname` to get your WAN interface name.
[edit] Success Report
Environment
- ADSL2+ service with static IP (no PPPoE or DHCP)
- TP-LINK TD-8817 ADSL2+ Modem Router, configured as bridge, web page at 192.168.1.1
- Linksys E1200v2 with DD-WRT 21676, LAN address 192.168.2.1, WAN admin port 8080
Objective
WAN access to modem on external IP port 8081 in addition to LAN access
(with WAN access to DD-WRT on external IP port 8080).
(with WAN access to DD-WRT on external IP port 8080).
Administration > Commands
[Save Startup]
[Save Firewall]
On builds newer than 42755 (Smart DNS implemented) you may need to change the above code and enter both lines under the firewall settings instead of splitting them:
Administration > Commands
[Save Firewall]
NAT / QoS > Port Forwarding
Application | Protocol | Source Net | Port from | IP Address | Port to | Enable |
DSL Modem | Both | 8081 | 192.168.1.1 | 80 | ☑ |
[so modem web page can be accessed from WAN on port 8081 (as well as LAN on port 80)]
Important: With WAN access enabled, set strong passwords in both modem and DD-WRT.
[edit]Alternate Method
An alternate way to execute the above commands on startup if you have JFFS enabled is the following:
- Log in via ssh/telnet
- create a file with the following content:
- save it as '/jffs/etc/config/modem.startup'
- create another file with the following content:
- save it as '/jffs/etc/config/modem.wanup'
- make them executable:
[edit] Tertiary Method
You can replace the 10.0.0.254 with an IP in the same range as the modem. If your modem is 10.0.0.1, you can use 10.0.0.254. If your modem is 192.168.0.1, you can use 192.168.0.254.
- Go to Administration -> Commands
- Enter
and click on Save Startup
- Enter
and click on Save Firewall
Notes:in the example given eth0 is WAN interface name. On the Setup --> Networking --> Port setup --> WAN Port Assignment you can check your WAN name and replace it according to your port configuration.If you have Guest WiFi (VAP) you should block guest access to your modem like this:
[edit]SSH Method
A good, secure method for accessing modem interface (configuration) is SSH port forwarding, which can be accomplished with the following steps (with Apply Settings on each screen):
1. DD-WRT build with working SSH
SSH broken in 21061, fixed in builds >21676
3d chess game full version. 2. Enable SSH service
DD-WRT: Services > Services > Secure Shell > SSHd > Enable
- No need to enable SSH TCP Forwarding for inbound connections.
- If Password Login is enabled, set a strong administrative password (12-14 random characters), and SSH login to the 'root' account with that password. (See Telnet/SSH and the command line)
- Recommend changing Port to deter port scanners (e.g., 8022).
3. Enable SSH remote management
DD-WRT: Administration > Remote Access > SSH Management > Enable
- Recommend changing SSH Remote Port to deter port scanners (e.g., 8022).
4. Setup route to modem
DD-WRT: Administration > Commands
Assumes LAN subnet 192.168.2.nnn and modem at 192.168.1.1 (change as appropriate):
[Save Startup]
5. Configure SSH port forward
See Example below.
6. Reboot DD-WRT and test
- ConnectBot is a good SSH client for Android.
- Mac OS X Terminal supports SSH. (guide)
- PuTTY is a good SSH client for Windows.
Example
- Assumes LAN subnet 192.168.2.nnn and modem at 192.168.1.1
- DD-WRT forward in PuTTY: L1080 192.168.2.1:80 (access at http://localhost:1080)
- Modem forward in PuTTY: L1081 192.168.1.1:80 (access at http://localhost:1081)
[edit]Notes
- Modem and LAN should be different subnets as in the examples above. It's not good network topology to have router WAN port and LAN ports on the same subnet (even when 'it works').

Summary
Standards:
RFC 2661
L2TP is a secure tunnel protocol for transporting IP traffic using PPP. L2TP encapsulates PPP in virtual lines that run over IP, Frame Relay and other protocols (that are not currently supported by MikroTik RouterOS). L2TP incorporates PPP and MPPE (Microsoft Point to Point Encryption) to make encrypted links. The purpose of this protocol is to allow the Layer 2 and PPP endpoints to reside on different devices interconnected by a packet-switched network. With L2TP, a user has a Layer 2 connection to an access concentrator - LAC (e.g., modem bank, ADSL DSLAM, etc.), and the concentrator then tunnels individual PPP frames to the Network Access Server - NAS. This allows the actual processing of PPP packets to be separated from the termination of the Layer 2 circuit. From the user's perspective, there is no functional difference between having the L2 circuit terminate in a NAS directly or using L2TP.
It may also be useful to use L2TP just as any other tunneling protocol with or without encryption. The L2TP standard says that the most secure way to encrypt data is using L2TP over IPsec (Note that it is default mode for Microsoft L2TP client) as all L2TP control and data packets for a particular tunnel appear as homogeneous UDP/IP data packets to the IPsec system.
Multilink PPP (MP) is supported in order to provide MRRU (the ability to transmit full-sized 1500 and larger packets) and bridging over PPP links (using Bridge Control Protocol (BCP) that allows to send raw Ethernet frames over PPP links). This way it is possible to setup bridging without EoIP. The bridge should either have an administratively set MAC address or an Ethernet-like interface in it, as PPP links do not have MAC addresses.
L2TP includes PPP authentication and accounting for each L2TP connection. Full authentication and accounting of each connection may be done through a RADIUS client or locally.
MPPE 128bit RC4 encryption is supported.
L2TP traffic uses UDP protocol for both control and data packets. UDP port 1701 is used only for link establishment, further traffic is using any available UDP port (which may or may not be 1701). This means that L2TP can be used with most firewalls and routers (even with NAT) by enabling UDP traffic to be routed through the firewall or router.

Quick example
This example demonstrates how to set up L2TP client with username 'l2tp-hm', password '123' and server 10.1.101.100
L2TP Server
Sub-menu:
/interface l2tp-server
This sub-menu shows interfaces for each connected L2TP clients.
An interface is created for each tunnel established to the given server. There are two types of interfaces in L2TP server's configuration
- Static interfaces are added administratively if there is a need to reference the particular interface name (in firewall rules or elsewhere) created for the particular user.
- Dynamic interfaces are added to this list automatically whenever a user is connected and its username does not match any existing static entry (or in case the entry is active already, as there can not be two separate tunnel interfaces referenced by the same name).
Dynamic interfaces appear when a user connects and disappear once the user disconnects, so it is impossible to reference the tunnel created for that use in router configuration (for example, in firewall), so if you need persistent rules for that user, create a static entry for him/her. Otherwise it is safe to use dynamic configuration.
Note: in both cases PPP users must be configured properly - static entries do not replace PPP configuration.
Server configuration
Sub-menu:
/interface l2tp-server server
Properties
Property | Description |
---|---|
authentication (pap | chap | mschap1 | mschap2; Default: mschap1,mschap2) | Authentication methods that server will accept. |
default-profile (name; Default: default-encryption) | default profile to use |
enabled (yes | no; Default: no) | Defines whether L2TP server is enabled or not. |
max-mru (integer; Default: 1450) | Maximum Receive Unit. Max packet size that L2TP interface will be able to receive without packet fragmentation. |
keepalive-timeout (integer; Default: 30) | If server during keepalive-timeout period does not receive any packets, it will send keepalive packets every second, five times. If the server still does not receive any response from the client, then the client will be disconnected after 5 seconds.Logs will show 5x 'LCP missed echo reply' messages and then disconnect. Available starting from v5.22 and v6rc3. |
max-mtu (integer; Default: 1450) | Maximum Transmission Unit. Max packet size that L2TP interface will be able to send without packet fragmentation. |
use-ipsec (no | yes | require; Default: no) | When this option is enabled, dynamic IPSec peer configuration is added to suite most of the L2TP road-warrior setups. When require is selected server will accept only those L2TP connection attempts that were encapsulated in the IPSec tunnel. |
ipsec-secret (string; Default: ) | Preshared key used when use-ipsec is enabled |
mrru (disabled | integer; Default: disabled) | Maximum packet size that can be received on the link. If a packet is bigger than tunnel MTU, it will be split into multiple packets, allowing full size IP or Ethernet packets to be sent over the tunnel. Read more >> |
To enable L2TP server:

Application Examples
Connecting Remote Client
The following example shows how to connect a computer to a remote office network over L2TP encrypted tunnel giving that computer an IP address from the same network as the remote office has (without any need of bridging over EoIP tunnels)
Consider following setup:
Office router is connected to internet through ether1. Workstations are connected to ether2.Laptop is connected to the internet and can reach Office router's public IP (in our example it is 192.168.80.1).
First step is to create a user
Notice that L2TP local address is the same as routers address on local interface and remote address is from the same range as local network (10.1.101.0/24).
Next step is to enable L2TP server and L2TP client on the laptop.
L2TP client from the laptop should connect to routers public IP which in our example is 192.168.80.1.
Please, consult the respective manual on how to set up a L2TP client with the software you are using.
Note: By default Windows sets up L2TP with IPsec. To disable IpSec, registry modifications are required.
Read more >>
At this point (when L2TP client is successfully connected) if you will try to ping any workstation from the laptop, ping will time out, because Laptop is unable to get ARPs from workstations. Solution is to set up proxy-arp on local interface
After proxy-arp is enabled client can now successfully reach all workstations in local network behind the router.
Site-to-Site L2TP
The following is an example of connecting two Intranets using a L2TP tunnel over the Internet.
Consider following setup:
Office and Home routers are connected to internet through ether1, workstations and laptops are connected to ether2.Both local networks are routed through L2TP client, thus they are not in the same broadcast domain. If both networks should be in the same broadcast domain then you need to use BCP and bridge L2TP tunnel with local interface.
First step is to create a user
Notice that we set up L2TP to add route whenever client connects. If this option is not set, then you will need static routing configuration on the server to route traffic between sites through L2TP tunnel.
Next step is to enable L2TP server on the office router and configure L2TP client on the Home router.
On home router if you wish traffic for the remote office to go over tunnel you will need to add a specific static route as follows:
After tunnel is established and routes are set, you should be able to ping remote network.
Basic L2TP/IpSec setup
This example demonstrates how to easily setup L2TP/IpSec server on Mikrotik router (with installed 6.16 or newer version) for road warrior connections (works with Windows, Android And iPhones).
First step is to enable L2TP server:
required is set to make sure that only IPSec encapsulated L2TP connections will be accepted.
Now what it does is enables L2TP server and creates dynamic ipsec peer iwth specified secret
Note: Care must be taken if static ipsec peer configuration exists.
Next step is to create VPN pool and add some users.
If there are strict firewall policies, do not forget to add rules which accepts l2tp and ipsec.
Now router is ready to accept L2TP/IpSec client connections.

L2TP/IpSec with static IPSec server setup
Ipsec/L2TP behind NAT
Consider setup as illustrated below
Client needs secure connection to the office with public address 1.1.1.1, but server does not know what will be the source address from which client connects. It is so called road-warrior setup.Our client will also be located behind the router with enabled NAT.
For the setup RouterOS router will be used as the client device behind NAT (it can be any device: Windows PC, Smartphone, Linux PC, etc.)
