Subject:   Can't telnet through ipfw...

I am trying to create a firewall in front of a single HP-UX server. I want
to allow telnet access from windows clients through the firewall and into
the HP... that's it.

After some failed attempts, I thought I would log ALL traffic in hopes that
I could see what was going on.  I did an "ipfw flush", then "ipfw add allow
log all from any to any" and attempted to telnet in. The telnet session
failed to connect so I checked the log. It showed tcp from me to the HP in
via the external interface, then tcp from me to the HP out via the internal
interface - as I would expect. But that's all - no return traffic - my
telnet client tries a couple of more times with the same result then fails
to connect.

My setup is:
	2.2.8-STABLE
	HP-UX and firewall internal NIC 192.168.100.x
	my clients and firewall external NIC 198.64.48.x
	/etc/rc.conf: gateway_enable="YES"
	/etc/rc.conf: router_enable="NO"

Am I having a routing problem?  Do I need nat?  Any pointers would be much
appreciated!

- Rick
