[Serusers] NAT Handling - SER behind a router

[TZieleniewski]

Hi!!

Right now I have SER based voip system but inside the local network.
I would like to enable the external internet connection.
Is it possible to realize the NAT handling but with SER-RTPProxy or 
SER-MediaProxy
not with the public IP so still in the local net but with the strict 
forwarding rules on the router.
where router ofcaurse has the public IP
So that for instance having SER and media proxy  inside local network but
with whole SIP traffic routed to SER and RTP to media proxy??

Is one of the above methods more recommened at the moment with ser2??

Thank you in advance

Best
