i thank you for your info ....
however i have one more question :
the way ipportfw works ...
if i need to redirect ports from valid ips to a local net ( ie 192.168.x.x)
will this get masqueraded inwards .... even if my policy doesnt allow it ?
or portfw will really simply redirect the port ?
or havew i misunderstood something ?
