Additional IP-adresses in 1 OpenVPN-tunnel [Newbie]

berserkargang

Hi!
First of all, I'm totally new to OpenVPN, so bare with me.

I'm using a tunnel from a VPNservice provider and at first I had no problems at all. I connected and got the intended public IP-adress. Now however, I've bought a additional IP-adress to the existing tunnel and as I understand i cant start another VPN-instance, but I have to route the secondary IP-adress from the computer with the openvpn-connection to another computer in my network. So do I have to change anything in my config file to make client "accept" another ip-adress? Currently it looks like this:

dev tap
remote 88.80.30.7
float 88.80.30.7
port 5180
ifconfig 88.80.28.224 255.255.255.128
route-gateway 88.80.28.129
redirect-gateway def1
secret prq.key
cipher AES-128-CBC
dhcp-option DNS 88.80.8.8
comp-lzo
route-method exe
route-delay 2

interesting VPN setup from the provider... have you tried connecting both PCs using the config file supplied by the VPN provider, i.e. your old pc using the config as described earlier, your new pc using a config with only the IP address (and possibly remote IP) altered?

berserkargang, using Windows you will have to install a routing software on the OpenVPN client, to route all traffic for the second IP to the other computer.

Tested that. Resulted in bunch of error messages in the log. The GUI said however, connected to x.x.x.x, but a check with myipaddress.com returned my regular IP from my ISP.

Ok, so the routing should be done by the openvpn client and not by Windows itself? Could u point me to a software like that?:)

I should also mention that im open to use a linux distribution if that would simplify the problem.

There are a lot of software routers to use. Most of them are commercial. If you can install lunux, it will be a better choose as you will have to add a single roule to the iptable.

I made a very artistic picture of my situation, so if that helps anything:)
