[KLUG Members] Port forwarding

[Jeremy Leonard]

I've used PCAnyshere through NAT. I was using a Nortel Instant Internet
device to do it though. I've also done it with Novell Border Manager,
and a SOHO firewall from Sonic wall. I don't know how to do it with
Linux though.

You need to forward from whatever IP the ppp0 device has to the
192.168.0.1 address... otherwise what's the point?
 
I'm also not sure if the PC Anywhere protocol actually works through
NAT either.. perhaps somebody else on the list has actually tried it.

I'm trying to get PC Anywhere to connect to our NT server, but I need
to forward ports 5631 and 5632 through our firewall. So far no luck, and
I'm not really sure where I'm screwing up. I've been digging through the
ipchains howto and tried ipmasqadm.
 
Our setup:
linux 2.2.14
device: ppp0 masq. to internet
device: eth0 to network
Acts as our mail server and caching dns.
 
I need to forward from 192.168.0.5(eth0) -> 192.168.0.1(NT) ports 5631,
5632. Do I need to change the firewall and mess with ipmasqadm? Or just
one of them?
 
Any pointers would be great,
Dan Downs
