EoIP over L2TP and NAT

RouterOS General
1

Hi,

I’m trying to configure an EoIP tunnel over L2TP VPN, one of the sites is behind a NAT. The result is that on one side tunnel is up but on the other (behind a NAT) is down.
What should I check/configure to make it work?

When there is no NAT between routers the tunnel goes up on both sides and it’s working fine.

Regards,
Piotr

If it’s really over L2TP, then I don’t see any reason why it shouldn’t work, you don’t have NAT there, it’s below L2TP and it already crossed it.

You can use L2TP with BCP… no need to use EoIP…

Well - my bad, the issue was with the firewall on one of the devices. Thanks for help.
