Question

I have added a static route:
interface = the l2tp vpn
target = 192.168.74.0 (my local network)
netmask = 255.255.255.0
ipv4 gateway = 192.168.124.254 (my mikrotik router:s ip in the vpn connection. I can ping it from rutx11)
metric =1
MTU=1500
Route type = Unicast

I am not able to ping anything on 192.168.74.x and the route does not appear in cli typing "route"
and it is not visible under "status"-Routes-general routes

What am I missing? It does not seem to appear in the routing tables

Comments

This is supposed to be so simple... tell the RUTX11 where to send and response to any traffic originated 192.168.74.x

That is the mikrotik router end with the transport ip 192.168.124.254

Answer 1

Turns out if I do the exact same thing with pptp it all works. Must be some kind of bug. I have tried factory reset several times, making less and less changes from original setup and for now thats my solution. Dont use l2tp.

Security on this link is not an issue so pptp will be fine.

Answer 2

Hi, could you please give more information about the interfaces you have now?

• Both of your L2TP IP addresses of your routers.
• Both of your LAN IP subnets and routers LAN addresses.
• Names of L2TP tunnel shown when executing ifconfig command on both sides.

Even a full topology would be helpful.

Thank you.

EB.

L2TP: 
Mikrotik = 192.168.124.254
RUTX11 = 192.168.124.12
LAN:
Mikrotik = 192.168.74.254 / 24
RUTX11 = 192.168.3.1/24
ifconfig:
RUTX11=

This setup is saved but not listed if i run rout or check the web gui.

In RUTX11 CLI add this route and check if you can ping:

ip route add 192.168.74.0/24 via 192.168.124.254 dev l2tp-client_Kla

Any luck on making that "IP Route" Permanent? I can't get it to work in the GUI so have to reapply it in CLI every day
