need help with ip-forwarding

[Nick <daye149@pacbell.net>]

this is my situation:

i have a linux box running 2.1, 2.2.15 with a dhcp service and ipmasq 
through ipchains

i wanna setup a webserver inside the network and have the http port 
forwarded through my firewall.

if i have ipchains i just need ipportfw right?  but dselect insists that i 
install ipmasq too?

how can i do this another way, or is this the only way???

outside ip - linux box (need to forward IP traffic for port 80) -- 
webserver (192.168.1.10)

thankx in advance
