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,  
	 

Ok - just to clarify, you are sucessfully pinging the webserver you want
to contact by name - is that correct? If so, that indicates that arp,
dns and routing are all 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   entoo).
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:)
	 

The only time i have seen this sort of thing is when there is a firewall
or MTU issue, but that would be unlikely here. Next stop is to run
netstat or a sniffer to see what's happening, but send the ping output
here first.
 
Rgs,
Adam
