Both routers are located in isolated ISP WAN 10.10.*.* and can access each other by WAN1 - WAN2.
Enery router serves its location and has its private LAN 192.168.x.*.
I need configure access from LAN1 to LAN2 and vice versa.
I'm trying to add a custom route between 2 routers from Router1 to Router2:
Router1
WAN - 10.10.218.1/255.255.255.0
LAN - 192.168.121.0/255.255.255.0
Router2
WAN - 10.10.170.18/255.255.255.0
LAN - 192.168.145.0/255.255.255.0
Router1 route table:
