First and foremost I am not a strong networking person but we do not have a network tech here in the office so I got charged with getting this setup and running. Here is the network topology:
Internet --> Cisco Router --> Internal Network (192.168.1.0/24)
On this internal network is a box that is running pfSense and has dual NICs (LAN and WAN) and it's sole purpose in life is to be an OpenVPN box; no other traffic moves through it. Now I have configured the ACL in the Cisco Router properly and am able to connect to the pfSense box with an OpenVPN client without a problem but that is as far as a client gets. The client can not see any of the boxes on the internal network.
Our internal network, as stated, is a 192.168.1.0/24 network and the address pool that I am using for the VPN is 10.10.11.0/24 (although, for some reason, the VPN Server is setting the mask to 255.255.255.252) I setup a 1:1 NAT so that requests from 10.10.11.0/24 go to 192.168.1.0/24 but things still aren't functioning. It seems to me like I need to do additional things to the Cisco to make this work but I am unsure as to what those things are.
Does anyone have any thoughts?
