yes, but symmetric nat would not forward packets to uac from the ip
address of the other ser even if it sends them to the external ip/port
of the uac.
Yes, and also (port-)restricted cone NAT won't work...
UPnP isn't widespread enough and cascading NAT won't work too (just want
to be shure to take into account all possibilities ;o) )
Ok, so the conclusion is to use a clustered solution with one public IP
and some kind of heartbeat.
Well, thanks for the insights anyway.
