[gentoo-user] Really weird network problem

[Robertas nera]

Hello,

I have some strange network problem: i can ping(icmp
works), i can arping(arp works), my dns works, btw routes also looks ok,
but then I try to open any site all i get is "request sent" message
from links, or connection broken to
x.x.x.x ... from conquer, and opera just displays empty pages,
and i dont think i have firewall(I'am quite new to
gentoo). Internet from windows and from livecd works without problems.
My best gues is it`s something wrong with tcp, maybe someone had a
similar problem
and could share their experience?
Thanks in advance. Sorry for english:)
