ipmasqadm portfw

[will trillich <will@serensoft.com>]

i used to have this working like a champ, but now it folds its
arms and laughs and evil laugh--

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'.

	# 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 (that is, from a public ip out on
the internet, trying to connect to port :7890 on my public ip
address) 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...
