[AG-TECH] AG and NAT traversing...

[Fabrizio.Berdondini at prototipo.it]

Hi all,
looking at the "AG 2006 Retreat" documentation I found some documents 
talking about NAT/firewall traversing, UDP tunnelling and so on. I tried 
to figure out if some information  they contained could be useful to solve 
our problems.
Our network infrastructure is going to be re-implemented, however, as far 
as now, our network is "sliced" in two subnets: one uses IPs on the 
172.17.246.xxx ranges, the other 192.168.2.xxx ranges. The UDP traffic 
between the two "slices" is cutted off, so a VenueServer placed in the 
172.17.246.xxx one allows multicast connection for users in the same range 
(as well as would do a VenueServer in the 192.168.2.xxx one for users in 
its same "slice") but audio/video streams for users connected to it, who 
are placed into the 192.168.2.xxx slice, cannot reach the ones into the 
172.17.246.xxx slice (and vice-versa). 
A second problem arises when connecting to a VenueServer placed onto an 
external network  via a unicast-bridge, because our network resided behind 
a NAT/firewall, which is known, prevents the right working of the AG 
quickbridge.
I would be gratefull if someone could give me some more information about 
how solving the problem of communication between the two slices (while 
waiting for re-implementation) and about some tool for overcoming the 
NAT/firewall limitation of the AG quickbridge: we also tried the "AG 
connector" but seems not working.
Thank you in advance for your help,
Faber B.
