====== OpenVPN and access to a remote IPCOP over IPCOP-to-IPCOP VPN ======
- Zerina Part
* You must have the latest Zerina Alpha (ZERINA-0.9.7a14-Installer.tar.gz as of this writing)
* In the Zerina Advanced Server Options screen and under the Additional Push Route section, in the first box type in the IP / Subnet of your Remote IPCop Green network. There are 6 boxes I only filled in the 1st box.\\ e.g. 192.168.0.0/255.255.255.0
* Saved Advanced Options
* Start your OpenVPN Server
- IPCop VPN Part\\ (I used IPCops VPN to connect my 2 Networks. If you used Zerina/OpenVPN then make the same changes there)
* You must create a 2nd VPN tunnel between your 2 networks. So, of course, you must make changes on both ends.\\ Basically you are going to make a duplicate Net To Net VPN tunnel that will connect your 2 sites. However, you are going to substitute your Local Green Subnet information with the OpenVPN subnet. What this does is creates a new entry in the routing table telling it how to handle packets from the Roadwarrior subnet. E.g.
* Local Green Subnet 10.1.99.0/255.255.255.0
* OpenVPN subnet 10.209.196.0/255.255.255.0
* Remote Green Subnet 192.168.0.0/255.255.255.0\\ My Setup * VPN Connection #1

Make sure both LANS are connected on both Net To Net VPN Tunnels. Reconnect your OpenVPN Client. Ping the remote network from your OpenVPN Client computer.
