I have a weird problem. I have an OpenVPN server up and running. When my VPN clients (10.0.0.x) try to connect to another machines (192.168.0.x), they fail (I tried netcat, telnet and SIP). If I perform a ping from the same client (10.0.0.x) to the same machines (192.168.0.x), it works, and suddenly the services (netcat, telnet, sip, etc) also start to work.
If you have
192.168.0.x machines behind VPN server, then you should probably add something like that to your OpenVPN server configuration:
push "route 192.168.0.0 255.255.255.0"
Issue is definitely strange, but my guess is that it is related to absent route between
10.0.0.x, VPN server and
