Question OpenVPN forward through firewall to VPN endpoint and rerouted back in?


Hey everyone,
I have just come across a networking problem/layout that has me absolutely scratching my head.

What I think we are going to do is as follows:

We have one connection in that is going to a router/firewall with a certain IP lets call it 142.2.2.20. That is going in on WAN1,and it is going to go through a port forward ( :6333 for example ) to 192.168.3.2 ( the Open VPN server or a VPN server such as ENDIAN community)

From that point it is going to be forwarded back and into the 192.168.2.x network that is in the Router box and connect to all the machines. Is this the way to do it?

Will a Roadwarrior/ client on the outside be able to connect then to the VPN server? and then from there connect to the correct box?


thanks,
Ronnie

Using OpenVPN server I open a port in the firewall that I define config file of the OpenVPN server and port forward to the server. Then enable IP forwarding on the VPN server so the private vpn network can reach the internal lan and on the internal lan's router I add a route to the private vpn network via the internal lan IP of the vpn server

The current idea for the network is this: using a linksys/cisco RV082 ( I think thats what its model is) and portforwarding all 1194 udp/tcp to the openvpn server which is an Endian Firewall.

Here is where things start to go wrong I think. The OpenVPN server on Endian is on the same network located at 192.168.2.203..... as the red interface. The green is 192.168.2.15 and the open VPN users use that as the gateway for the OpenVPN.

Using another client on an outside network, I start a OpenVPN connection to the rotuer which then forwards me correctly to the Endian box. On the Endian box I can see the user trying to connect, but on the client all I get is TLS handshake timeouts. Now looking at the Endian logs it looks liek it is workign correctly btu it can't find the clienet host..

This looks like a routing problem to me.. any help would be great.
