Hi all I have troubles with routing between my VPN servers (using
openvpn and tun pseudo-devices) in 3
offices. Problem desc: I can't ping hosts in 192.168.1.0/24 network in
office3 (pings don't go to 10.1.0.1 and 192.168.2.0/24 -> 192.168.1.0/24).
Ping probes work fine between another internal networks to
192.168.2.0/24.
When run on router in office2 "tcpdump -i tun2" (interface to office1)
and "ping 192.168.1.1" I see ping requests to ping 192.168.1.1 on
tcpdump output, but no ping reply.
