blaser I have an openvpn server on my home router running dd-wrt, everything works fine. My subnet at home is 192.168.1.x and I'm pushing vpn ip address to the client of 192.168.1.100. The problem starts when I travel to Europe and I want to connect to the home vpn from the hotels. Many hotels in Europe are using 192.168.1.x or similar, some of them are using mask of 255.255.0.0. When I connect through the vpn I have a problem of local network IP vs. home IP. Any idea how to resolve it?
janjust change your home network to be anything but 192.168.1.x ; there are plenty of addresses to choose from, e.g. 10.200.200.x 172.17.100.x (i.e. any 10/8 and 172.16/12 address)
janjust you *might* be able to work around it using some iptables double NATting magic, but I'd recommend to NOT try this. This is not an OpenVPN issue but a generic IPv4 routing issue.
