I have n810.. I brought my laptop to my parents house today and connected via one of their xp machines.. (no clue what version it was running or what service pack).

I simply enabled xp rdesktop on their router (same port 3389 on their router anyway).... And it worked like a charm. (As backwards as it is.. I figure if I can connect via a public ip address then that is a good start).

So to clarify. I brought my laptop to their house.. connected from their computer to my public ip and everything worked fine.

At my house I have tried to connect from my n810 to my laptop which is at my house.

I have also tried to connect from a computer with rdesktop at school to my laptop at my house.

So far only connecting via public ip has worked from my parents computer while my computer was at their house.

As to ISP we live in different cites but, have same ISP. We both have bellsouth. I live in hammond they are closer to baton rouge (central area).

They got their router a long time ago.. mine is a newer model router.. but, its the same service. We both have the highest (non business) connection to the net. They have phone and other services which I don't use.. but, that aside I got all the same internet privilges they offer the 'top package' internet customers.
