Issues accessing inside resources using OpenVPN.
One of my projects I'm working on is creating a Linux (Ubuntu Server 12.10) PC as a Router/Firewall/Gateway (Which is working great!). I'm also going to setup the system to act as a VPN server using OpenVPN. I seemed to be having an issue accessing my server when using the VPN. The steps I've completed:
Configured certificates for both the server and the client.
Install and configured OpenVPN on a Microsoft Windows 7 (64Bit) system.
On the outside, I've connected, authenticated with the VPN server, and been assigned a IP address.
I can ping and even access the linux system (via SSH and webmin) using the linux system's tunnel address, not it's inside address.
I cannot ping or access any device on the inside.
I'm guessing it's a routing or firewall issue. My issue is that I'm a novice with the linux firewall (iptables) and how to properly permitting VPN clients access to the inside network.
Any suggestions would be great!
