thanks, for both of you for pointing this out.  i was obviously on the 
wrong track here.  since i see the rtp traffic via tcpdump, i'm going to 
ask the other gw's sysadmin to see into this, maybe there is some 
logging on the other side.

this is a private pilot network for testing purposes, no internet 
connection, no nat, no firewall.  it's like the 90s :)

thanks for your comments.
