I have searched the site for a close situation, I didn't find one. We have two sites connected by VPN as follows:
LAN1 (192.168.18.0) VPN Server - 192.168.18.4
LAN2 (192.168.19.0) VPN Server - 192.168.19.4
The problem is that from LAN2, any client can ping/reach 192.168.18.4 in LAN1, but not any other clients in LAN1. If I go to 192.168.19.4 itself in LAN2, I can ping/reach any client in LAN1.
What can I adjust in the routing to enable any client in LAN2 to see any client in LAN1. Any help will be appreciated.
