[arm-allstar] Linking behind the firewall

[Fred Moore]

Jim.. I wonder about something that could lead you to a fix. 

You indicate that each node is on the same LAN with different ports, but
you say others can connect to you.  For some reason I can't remember I
know that nodes on the same subnet can not talk, but can't remember the
reason.   I wonder how an outside port can be NATed to two different ip
addresses inside..  That port being 4569 UDP.  

Second comment.. ports are not tied to the router, IP addresses are..
the router can NAT different ports to specific IP addresses, but there
is a conflict if the same port is natted to two different IP
addresses..  Don't know if the routing table is just picking up the
first address in the table and looping you back to yourself, or what is
happening.. I would suggest you fire up a trace utility an actually see
what is happening, that will show you..  traceroute might be your friend
here if you don't know how it works. here is a link

I would look at that area..  regards.. Fred
