Trying to copy files across an IPSEC vpn

I'm trying to figure out how to copy files across my vpn which goes from Shamrock to NBC.

private path 192.168.47.0 ---> 192.168.38.0

public path 208.115.11.214 ---> 208.115.24.30

The copy command I am using is:

copy c:\aaaa\COPYTEST.txt \\192.168.38.30\aaaa


192.168.38.30 is Mary's computer at NBC. It is named rover.

All I ever get is "The network path was not found."

The latest thing I tried was to add the following line to atlantic on the NBC side:
195 permit ip host 208.115.11.214 any

I realized that I don't know what king of protocol (tcp? udp?) that a Windows "copy" command would generate over the wire. I figured ip would be a good catch-all but, but it's still not working. But maybe it should be that I allow any IP from 192.168.47.0 ????? I'll try that in the morning, I'm out of time now. But the vpn should allow things from 192.168.47.0 to 192.168.38.0 by its very nature shouldn't it?
