Hello, I encountered an issue with my routing:
Devices connected to Router1 use the 100mbps link (eth0, 1.1.1.1) by default, but for l2tp (for 192.168.1.0/24 and 192.168.2.0/24 to communicate) It has to use the 1gbps link (eth1, 2.2.2.2) instead to communicate with Router2, which it fails to do and uses the 100mbps link instead, despite l2tp being established specifically between 2.2.2.2 and 3.3.3.3 IP's.
Below is a "map" of two networks, where Router1 doesnt use the proper interface to communicate with Router2 via L2TP.
