Access to some webservers through firewall

Hello!

I have configured my firewall with iptables to basically let in only
answers on my requests, which works fine at about 95% of all webservers.
But when I'm trying to access some sites my firewall blocks the answers
like this:

Nov 26 10:04:18 internet kernel: DROP-TCP IN=ppp0 OUT= MAC=
SRC=213.83.13.35 DST=222.82.183.145 LEN=1490 TOS=0x00 PREC=0x00 TTL=54
ID=8559 DF PROTO=TCP SPT=80 DPT=1789 WINDOW=15972 RES=0x00 ACK URGP=0

which is correct, because I was trying to contact www.bahn.de
(213.83.12.10). I think that they have a load balancer who sent me to
that ip-address, but as my firewall did not open a connection there it
blocks the packages.

Any ideas what I can do about that? By the way, I had the same problem
with suse-firewall, too.

Best regards,

Ralf Ronneburger
