Finally got some time to sit down and scratch on this problem.
I am able to use openvpn to log into other location and ping target IP via Dyndns. ICMP returns are seen and are also seen in pftop.
Then, I used radmin at other location, again, via openvpn, and attempt to log into system here, where I am. No connection error seen at remote location. However, pftop see's the attempt.
I then uninstall Commodo firewall, restart, and re-try. Again, no connection error, pftop see's attempt.
I then, using windows 7, navigate to windows firewall and check the permissions. I almost mistake radmin viewer as the correct program, but this is incorrect as I am looking for rserver, which is located, in my system, inside the syswow64 folder.
Rserver is not listed as allowed. Rserver added as allowed and… bread, butter and cheese..it works!
So, I apologize for being too quick to hit RC2. She has had some rough days in the past, but this young lady is maturing nicely. :)
