L2tp client as a gateway?

Question

linux

Guys, help out pliz advice. There is an l2tp server on Mikrotik, an instance on aws is connected to it by the l2tp client. Is it possible to implement a route to the Internet for a machine from the local network of Mikrotik, so that the aws instance acts as a gateway?

Answer 1

Mark traffic from this machine and, based on the marking, wrap it in an L2TP tunnel.

/ip firewall mangle add action=mark-routing chain=prerouting comment="To AWS" src-address=<Mashine IP> new-routing-mark=aws_route passthrough=no

/ip route add comment="To AWS" distance=5 gateway=<L2TP_AWS_IP> routing-mark=aws_route

I'm writing from memory - the syntax may not be correct...
On the AWS instance, you need to enable IP packet forwarding and configure src-nat.

Answer 2

ATP is great, it worked.
