Client IP in 'REMOTE_ADDR' through OpenVPN



  • Hi all,

    A client is using a basic OpenVPN access vpn to gain access to an internal LAN behind one of our pfSense boxes. They are given a 10.10.252.0/24 IP upon connecting. The internal network that access is granted to is 10.10.48.0/24.

    Hosts on the 10.10.48.0/24 address are seeing the clients IP (as REMOTE_ADDR) as their public WAN IP's from their ISP/Office etc. It would benefit us, and their configuration/coding, if the private hosts would see REMOTE_ADDR as the clients OpenVPN Client IP, so 10.10.252.x.

    Can this be done? Thanks.



  • You could use NAT 1:1 on the pfSense box.

    NAT the VPN clients onto some useful network range, ie hide whatever remote address they're using.
