[Novices] IPCop question

[Greg Mason]

I've got an IPCop box setup, and two machines connected to it.

I'm trying to move files from one to the other (backup before a  
reinstall).

One machine is SuSE 8.2 (the machine getting a reinstall), and the  
other is my PowerBook (Mac OS X 10.4.1).

The PowerBook is on the wireless, Blue. The SuSE box is on Green.  
Neither box can ping the other, connect via FTP, SSH, SMB, etc.

I've looked under the DMZ section of the IPCop config page, but I'd  
just as soon have all traffic flow between green and blue, regardless  
of what port it's on, and where it's going to and from. I've probably  
just missed something obvious, and I'm going to prolly kick myself  
when I see what it is...
