ipmasqadm portfw -a ... stopped working?

[will trillich <will@serensoft.com>]

we're trying to establish port forwarding so that a box internal
on our lan (192.168.1.2) can serve requests through the
firewall, from 'out there'.

i haven't even done apt-get upgrade lately -- and now
ipmasqadm 'portfw' isn't working. (i may have missed a step, but
/usr/share/doc/ didn't help ring any bells...)

	# ipmasqadm portfw -a -P tcp -L [PUBLIC_IP] 7890 -R 192.168.1.2 80

	# ipmasqadm portfw -ln
	prot localaddr        rediraddr       lport    rport pcnt  pref
	TCP  [PUBLIC_IP]      192.168.1.2     7890     80    10    10

well, it LOOKS like it's up, but--

	# nmap [PUBLIC_IP] -p 7890

	Starting nmap V. 2.12 by Fyodor (fyodor@dhp.com, www.insecure.org/nmap/)
	No ports open for host server ([public_ip])
	Nmap run completed -- 1 IP address (1 host up) scanned in 0 seconds

which is bolstered by the fact that if i try to connect to
public port :7890 from outside i get deafening silence (unable
to connect to host).

is there another step i've forgotten? i'm on potato 2.2.17 and
this was working earlier...

"[PUBLIC_IP]" is, of course the client's actual ip address, if
you wondered... :)

DEBIAN NEWBIE TIP #73 from USM Bish <bish@nde.vsnl.net.in>
:
Looking for a way to CAPTURE A TRANSCRIPT OF SOME COMMANDS?
Easy!  To catch anything from the screen when it scrolls by,
use "script":
	script file-to-save-transcript-in.txt
	<command>
	<command>
	exit <== don't forget this!
(It spawns another shell, and displays everything so you
can work -- but it also saves the output in the file at the
same time.) Then "pager file-*transcript*" to review it. Or
email it. Or edit it to include in a manual you're writing.
