Hello *,
I am Running Debian GNU/Linux 3.0 with Kernel 2.4.27 and I have
following Network since 6 years:
----8<----------------------------------------------------------------
Internet Access with dynamic IP Address

+--------+--------+
| Netgear DM602A |
+--------+--------+
|IP 192.168.0.1

|NW 192.168.0.0

Now I have following problem:
If I am on the Sub-Net-Router I can reach the Internet and all
subnets without any problems. I can reach the Sub-Net-Router from
the Internet via SSH.
'ping', 'wget' or 'ssh' between the subnets is working too.
But if I am in one of the Sub-Nets, I can not get anything from the
Internet.
I have installed tcpdump and monitored eth2 and eth0 on the "Sub-Net-
Router" and gotten following:
I am in the "private network" on my Workststion <michelle1> which
has the IP 192.168.0.71 and the gateway 192.168.0.65. Now I 'ping
-c 2 www.debian.org' and can see, the DNS-Request is coming into eth2
and goes to eth0 out. The traffic LED on my Netgear DM602A is now
blinking and I can see, the package is coming back into eth0.
But now, my "Sub-Net-Router" stops forwarding the package back via
eth2 to my Workststion <michelle1>...
What I am missing here ?
The bad thing is, the router was working for more then 6 years (Linux
2.0.38 and now 2.4.27)
Any Ideas ?
Greetings
Michelle
