What is the gateway address of the ipv4-network? Do you mean the ocserv address, or the address of the gateway of your network? If you mean the ocserv address that can be seen in the vpns device in the server. If however you mean the gateway of your network, then your settings: > It contains the following lines in ocserv.conf: > ipv4-network = 192.168.100.0 > ipv4-netmask = 255.255.255.0 > dns = 192.168.100.1 are wrong. There you should specify the network to be used by ocserv, not your LAN network addresses. These two networks will communicate by setting the appropriate routes. regards, Nikos
