ports and www.debian.org

[Andreas von Heydwolff <pirmin2@gmx.net>]

Hello,

with an iptables firewall set to a default REJECT I can load almost 
every web site but www.debian.org which gives me timeouts. Opening ports 
7 echo/icmp or 113 auth doesn't make a difference. When I open all ports 
for 192.25.206.10 the pages load immediately.

What ports would I have to open specifically if I don't want make a hole 
for the whole IP address? I was cracked a few months ago and spoofed 
kernel.org packages (checked with their sysadmin) keep appearing now and 
then, so I'd rather be safe than sorry.
Regards,

Andreas
