Server Not Responding

I have a strange problem.

My apache server 2.0.49 on Suse linux has been running fine for months
now then suddenly i have the following problem:
I can access my server on my LAN using the 192.168.60.10 IP address but
I cannot access it anymore from my WAN using my external IP address.
I've checked the log on my router and HTTP pakets (port 80) are being
forwarded to my apache server. However when i look at the access log i
cannot see any request being passed to the apache server when i try to
contact from WAN and obviously i can see the request when connecting
from the LAN.

I have no iptables setup and as far as i know - and i'm the only one
using this machine - nothing has been modified in terms of
configuration.

Any ideas how i could troubleshoot further to see what is blocking the
HTTP packets when coming from the WAN?

Thanks

I'll have a look.. first time i use this tool.

BTW - i can remote connect through the WAN to my linux box via the
HTTPS port.

nothing in or out using tcpdump on port 80 but obviously i can see all
the traffic on the https port since i'm remotely connected.

I have checked once more on my router - a netgear dg824m - and i can
see the packets being forwarded:
"Thu, 2005-11-17 19:42:35 - TCP packet forwarded - Source:152.*****
,5314 WAN - Destination:82.***,80[HTTP] LAN - [Inbound Rule(1) match]"

My router rule definitely redirects to the correct LAN IP address but
the log do not show it so i cannot be sure at 100% that there is not a
problem there.

Any idea?
Thanks

one more thing when i run tcpdump i got the follwing summary:
963 packets captured
1357 packets received by filte
391 packets dropped by kernel

could my packets be dropped by the kernel?

I'm really puzzled because my configuration is really simple - isp -
router - server and it worked for months... maybe my router is
faulty...

Thankd for the help.
