OpenVPN Support Forum

Hi,

I am running openvpn server as VPN provider. I got an IP pool of /24 now I want to offer dedicated IP type service to my clients.
I have setup a X.X.X.2 to main interface and other X.X.X.3 to X.X.X.254 configured as virtual interface.

There are 2 issues:
1- I want to run openvpn on 0.0.0.0/0 to it only connected on primary IP and when i try to connect to other IP it give TLS error.

2- I want to route user through the same IP on which user is connected, for example USER-A connected to X.X.X.10, he should see X.X.X.10 on ipinfo.io

Please guide me how can I achieve this.
thanks

Regarding 1, I think you need to add --multihome to your configuration, otherwise replies will always go out via the primary IP and thus receiver will be confused.

Regarding 2, this is not something that OpenVPN controls. It's about how you configure NAT on your system. Basically you want to configure a SNAT/MASQUERADING rule on a per-client basis with the IP to use being the one where the connection was received. Maybe a --client-connect script has all the variables to let you write a custom iptables rule.
