I have two ethernet WAN links and i want to build two L2TP tunnel to my VPN server from two differnt WAN links.
If the IP of the remote endpoints are known, simply make a static route to reach each endpoint, using the respective WAN link.
but the remote endpoints are same. In this problem is in reverse routing.
You need to bond the 2 tunnels. Search for bond in linux.
