[Serusers] mediaproxy: Can I tell if two UAs are behind the same firewall?

[Marian Dumitru]

Paul,

you just have to check the NAT flag if it's set. it's the flag you set 
when a request is detected as NATed. The same flag is set by lookup() if 
the returned location is NATed.
Default is flag 6, but you can configure it via usrloc module param 
"nat_flag".

Best regards,
Marian
