No, you don't need all that. The gateway should be set to the same gateway everything else is on your network. Well, one thing you could do is DMZ the Aspire and see if it works or put it in front of your firewall.

"Mind you the VPN works ok with EVERYTHING else, jut NOT with the Aspire, so I dunno why that would make you think it was an issue with the VPN...?"

Because it works internally and not externally pointing directly to an IP/UDP connectivity issue. Troubleshooting 101.
