How to open UDP ports in MASQ server?

["Michael D. Crawford" <michael@geometricvisions.com>]

Hello,

I am using IP Masquerading on my debian box to share my net connection with the 
other computers in my house.  I need to open both a TCP port and a UDP port to 
allow a computer on the internal network to run a certain program.

I've had a look over some of the network howtos and find the information very 
confusing.  There is just too much information there to figure out how to do 
something simple.

I could probably figure out how to allow an exception for a TCP port but UDP, 
being connectionless, wouldn't work right with IP masquerading.  But only one 
computer in my house is going to use this UDP port, so if there is some way I 
could hardware the destination internal IP address, so that all UDP packets sent 
to this port would get sent on to my internal box, that would work great.

I'm running I think kernel 2.4.20, and it's a powerpc Mac if that's important.

Thanks for your help!
