I guess I didn't explain very well. :-) -redirect_port will work for static mappings. I have no problem with that. But let's say i have a lan with 10 computers, heck even just 2 computers. It would appear there is no way to make dialpad.com work for all computers at the same time. However, with linux's ipmasqadm, it appears that there is a way. It uses outgoing connections to port 7175 to trigger a mapping for returning traffic to ports 51200, 51201, etc. Well, that's what I gathered from the config snippet. I don't have access to a linux box so I can't test out. If ipfw can do this, I'd love to see how. (Not bashing ipfw-- an honest question.) jon >>>original email follows At 2:51 PM -0600 3/7/00, Joong Kim wrote: >On dialpad.com's faq page they say I can issue the following ruleset >to ipmaswadm to apparently enable forwarding of received packets to >the correct internal host: > > /usr/sbin/ipmasqadm autofw -A -v -u -r udp 51200 51201 -c tcp 7175 > /usr/sbin/ipmasqadm autofw -A -v -u -r tcp 51210 51210 -c tcp 7175 > >I don't see that there is a way to do this with natd and ipfw, but >wanted to check to be sure.
