Michael, Personally I always use OpenVPN server "Topology: [subnet]" provided all your clients support that. The old [net30] topology can be confusing.
If using an OpenVPN subnet IP for the web interface address is still a problem, you may try using the LAN internal address (assuming you have one defined) Network -> Firewall -> Firewall Options: _x_ Allow OpenVPN Server tunnel to the [ 1st ] LAN Interface(s) and on the OpenVPN server config ... "push" route 192.168.110.1 255.255.255.255 so with the above and 192.168.110.1/24 was your 1st LAN interface on the server, have your remote OpenVPN clients use 192.168.110.1 to reach the server's web interface. On my lab bench test boxes I just tried this ... MacBook (192.168.222.215) -> (LAN eth3) AstLinux w/OpenVPN client -> AstLinux w/OpenVPN server (LAN eth1.10) AstLinux w/OpenVPN client (tun2): # ip r ... 10.8.1.0/24 dev tun2 proto kernel scope link src 10.8.1.2 192.168.222.0/24 dev eth3 proto kernel scope link src 192.168.222.1 192.168.110.0/24 via 10.8.1.1 dev tun2 ... AstLinux w/OpenVPN server (tun0): # ip r ... 10.8.1.0/24 dev tun0 proto kernel scope link src 10.8.1.1 192.168.110.0/24 dev eth1.10 proto kernel scope link src 192.168.110.1 192.168.222.0/24 via 10.8.1.1 dev tun0 ... OpenVPN Server config: "raw" client-config-dir /etc/openvpn/ccd /etc/openvpn/ccd/client: iroute 192.168.222.0 255.255.255.0 "raw" route-gateway 10.8.1.1 "raw" route 192.168.222.0 255.255.255.0 "push" route 192.168.110.0 255.255.255.0 Network -> Firewall -> Firewall Options: _x_ Allow OpenVPN Server tunnel to the [ 1st ] LAN Interface(s) In this test example I was able to reach the "AstLinux w/OpenVPN server" web interface from the MacBook (192.168.222.215) by using either 192.168.110.1 or 10.8.1.1 .
