Hi,
I'm using OpenVPN on two ERLite routers for a site to site connection. I can ping the remote router IP from either end, but can't ping the LAN devices. This pinging is directly from the routers using ssh.
Router 1 (Remote Site):
eth0 wan (static ip) x.x.x.172/28
eth1 Target LAN (this is what i want to communicate with, this is also the only private subnet that cannot change) 10.10.10.1/16
eth2 private LAN 192.168.10.1/24
vtun0 OpenVPN Client/Server (this works fine) 10.11.0.1/16
vtun1 OpenVPN Site to Site 10.30.30.1/32
Router 2 (Local Site):
eth0 WAN1 static IP x.x.x.171/28
eth1 WAN2 dhcp failover (left unused for now)
eth2 Target LAN 10.15.15.1/16
vtun0 OpenVPN Client/Server (this works fine) 10.16.0.1/16
vtun1 OpenVPN Site to Site 10.30.30.2/32
