I reinstalled my Debian Sarge with kernel 2.6 and now other computers connecting throught it can't access some websites (like www.microsoft.com, www.msn.com, can't use MS MSN Messenger - but Gaim works just fine). The server itself can access www.microsoft.com for example.

I'm using the same rc.firewall.stronger which I used before with 2.4 and everything worked fine.

Dhcpd server ja resolv.conf seem ok, so I guess it must be the firewall or interfaces config.
