Thanks. I got this message:

Nat with Independend Mapping and Port Dependent Filter - VoIP will work with STUN
Preserves port number
Does not supports hairpin of media
Public IP address:
I have set "Symmetric NAT Handling" to "No" now, and have set-up STUN in my VoIP device.
Could anyone explain to me what the difference is between "Symmetric NAT Handling" and "STUN"?
