[OpenSIPS-Users] Mediaproxy and SDP-mangle

[Cosimo Fadda]

Hi everybody,
I have a sever inside a DMZ with a private IP address (10.20.30.40) 
reachable from the outside with a Public IP (90.80.70.60) Natted 1:1 to 
the private IP.
I want to setup mediaproxy on this server, but since I cannot configure 
it with the public IP, in the resulting SDP messages the Private IP will 
appear .
Can I use the function:

sdp_mangle_ip("10.20.30.40","90.80.70.60");

to correct this behaviour?
Or there is another way to run mediaproxy in this scenario?
Thanks in advance,

Cosimo
