Url not found ....

[Patrick Petermair <captain.nuke@gmx.at>]

Hi!

I've installed a firewall/gateway with RedHat 7.3 and iptables. I've set up 
masquerading for my internal lan and some basic firewall rules.
Everything works fine (icq, ftp, http,...) but there is ONE homepage which I 
cannot acces (a friend of mine can).

http://stud4.tuwien.ac.at/-e9625216/html/projects.html

When I try to access this page with client in my lan all I get is "not found - 
The requested URL [...] was not found on this server."
After taking a look in my firewall log I found this entry:

Jul  6 22:45:11 wormhole kernel: IN=ppp0 OUT= MAC= SRC=193.170.75.21 
DST=213.225.44.140 LEN=52 TOS=0x00 PREC=0x00 TTL=57 ID=46360 DF PROTO=TCP 
SPT=80 DPT=36827 WINDOW=32768 RES=0x00 ACK FIN URGP=0

And if you try to ping stu4.tuwien.ac.at you'll find out, that the IP is 
193.170.75.21 - so the answer from the server gets dropped at my firewall.

So the big question is WHY? All homepages I tried so far are working, but not 
this one, so I doubt that it's a problem with the firewall rules.....

Any hints/comments?

Regards,
Patrick
