Thomas,
I have the same problem, except that I have single IP and my PC reboots
when it get long time idle, and I dont know how many time. Even with firewall
not running. Probably when I back to work next morning it will be down again.
When I was with 3.5-STABLE it was all ok. Now with 4.1.1-STABLE these
reboots are forcing me to "downgrade" to 3.5-STABLE.
I dont know whats the problem. Its all ok. I dunno if its natd, or some
other deamon I run here. Or if it is just the fact that this machine is a
gateway or something in the hardware.
If you know if there is any kind of test I could do to try to discover
what is wrong.
Any kind of help is valuable now. =)
