OpenVPN Support Forum

All,

I need help with my openVPN configuration. Hope to get help here.

I am running a Linksys WRT54Gv4 Router with DD-WRT (15200 vpn-small build) as my openVPN server with the following specs.

WAP IP: 192.168.20 (connected to an internet facing router)
LAN IP: 10.100.2.200/24

There is a another subnet 10.100.1.200/24 connected to the internet facing router that has various devices connected to it, printers, media, file servers, NAS etc.

Here are my OpenVPN Configs

From the outside, I am able to connect to the OpenVPN server, and get an IP address assignment. However, I cannot see any of the devices (including the Router acting as the OpenVPN server) on the 'internal' network.

In looking at the tracert (to the router IP) output, it looks like I am still going over the internet to access the internal IP. A visit to the 'whatsmyip.org' site shows the WAN IP of my location, not the WAN IP of the 'home network'. I am guessing that once I address the WAN IP issue, I should be able to see the devices on the 'home network'. Needless to say, even thought I have a 'connection', it is not functional.

Any thoughts on what might be wrong with my configuration. Am I missing something critical, that would help establish the VPN ?

Thanks.

This forum is not very helpful. Is there a shortage of knowledgeable members to help others in need ?

I have sinced solved my problem.

there is definitely a lack of time for some of the people that help here, please feel free to post how you fixed your setup / stick around and help if you would like to

I was using the configuration on a test machine that had not been rebooted for a while. There were some conflicting route rules from previous tests. Rebooting the machine, cleaning out the route tables helped solve the problem.

Good to be back and functional.

Regarding helping, I will be more than happy to do so wherever I can.
