Which Ports needed for L2TP/IPsec-Server, Portforwarding on Fritzbox

Hello,

I want to setup a L2TP/IPsec-VPN-Server on my MikroTik-Router.

The MikroTik-Router is connected to a FritzBox7490 which is connected
to the internet.

At the moment I don’t know which ports I have to forward to
the MikroTik-Router for a working VPN-connection.

Can somebody help me with this issue?

You should port forward ports UDP 500,4500 and 1701…
However am not really sure that it will actually work…

Port 1701 does not need to be forwarded, it’s for L2TP packets and those will come encrypted in packets to port 4500.

Right @Sob… missed that

Did you ever get this working? I need to do the same thing.
