I have serious problems with my firewall/router running Bering rc3.
I run the 2 interface configuration masqing my internal network on one
nic to an internet connection on the other nic. Everything seems fine
from the routers point of view, and everything seems to work from the
internal network. (I have ran this configuration since april)

Now to my "weird" problem.. 

I run a web server in my internal network ( I know this isn�t the way to
do it.. I should be using a DMZ, but if I cant get it to work with 2
nic�s, then why should it work with three?..) Anyway.. I forward all www
connections from the firewalls internet nic to the webserver using 

DNAT            net     loc:192.168.1.2 tcp     www

Where 192.168.1.2 is my webserver. 

Now when connection my firewall from any host on the internet SOMETIMES
it puts me through to my webserver and everything seems fine. But 99% of
the time, it seems like the router doesn�t work at all (ie doesn�t
forward and/or doesn�t respond).
Mostly it works a while after bootup, but then it stops working.
Meanwhile everything seems fine from the internal network.

Now I have tried configuring the router to respond to
ping/tracert/traceroute so that I can check if it responds, but it stops
responding whenever it likes. The router logs doesn�t record any icmp
connections when trying to ping it from the internet..

My PING config:
#
# Accept PING connections
#
ACCEPT          net     fw              icmp    echo-request
ACCEPT          fw      net             icmp    echo-request
ACCEPT          loc     fw              icmp    echo-request
ACCEPT          fw      loc             icmp    echo-request
#
# Accept Tracert response connections from firewall
#
ACCEPT          fw      loc             icmp    echo-reply
ACCEPT          fw      net             icmp    echo-reply
#

I have had the same problem with Bering rc2 as in rc3. I hardly thing
shorewall has anything to do with this since it works sometimes. 

I have no idea why this is happening? Can it have something to do with
my hardware? (eg my nic?) I use 8390 and ne2k-pci (for my internet nic a
KTI ET32 10Mbit PCI card)

Anyone got an idea about what could be wrong?
(No.. it�s not the problem with the nics connected on the same switch..)
