On my custom built kernel nat seems to be stable.
My N900 is connected to a 3G network sharing the connection via usb networking with my laptop just now.
I'm downloading a 85Mb file at about 380Kb/s without issues.
In the next few days I'll test with my campus wifi network and report what happens at higher rate.

I'm just a bit worried about the custom kernel, the device restarted twice at the very first boot, and currently I can read an opses in dmesg:

I'm very new to N900 hacking, and if that depends on a my mistake I hope to not break my phone
