[asterisk-users] NAT: RTP Path Optimization

[Patrick Cervicek]

http://lisas.de/~patrick/temp/rtp-optimierung.png

Everything is working fine in my Setup, but I want Extern1 to talk to 
Extern2 directly whitout going over Asterisk as the uplink is slow.

When I set for Extern1/2
canreinvite=yes
it works, but "Intern-2-Extern" doesn't work because Asteisk gives out 
the private IP-Adresses of Int1/2

I defined
localnet=10.0.0.0/255.0.0.0 (Private LAN)
but this doesn't help.

Ideas, how to handle "Extern-2-Extern" (RTP bypass Asterisk)?
Do I have to adjust "nat" somwhere?
