So?
Any word from D-Link on what "roughly equivalent" to Full Cone allows?
I find it difficult to believe that this is such a hard answer to dig up. I have only been assured that it "should" allow "most" unsolicited connection requests, but nothing definitive. Perhaps someone can suggest one knowledgable D-Link Agent that could cut through the confusion at the Tech Support Offices.
I have found success in advertising the server on the Master Server Browser for all clients to see me,
AND am apparently getting solid connections from clients that join my server through Master Server Browser.
My main feedback tester had install issues on his PC that clouded the diagnostics, and after his reinstall his finding me/connecting was unhampered so far as we can tell.
The NAT test still pops up an error warning, under port forwarding, DMZ, Virtual Server, OR Triggered Ports mode. It is starting to look as though the test is flawed... and encouraging home servers to jump ship to paying for a server rental.
The only loose end still remains, to determine exactly what connections " Endpoint Independant" WON'T allow.
By the way...Reinvented,
Turns out I was right. Ports 6500,7777,and 13000 ONLY for hosting a server.

So it appears your source for UT3 ports needs a little reality check. They may want to contact Epic's official forums to make their data even remotely relevant. Server Setup-->
