STUN can not work

hi,everybody

I have a problem.

I configured my Media Proxy,and it works fine,and also cnfigured my STUN server,set Local Server Enabled.

Two clients can start a phone call.But two clients from different LAN can not establish phone call.

I capture packets and find that Media Proxy works fine,but Local STUN Server do not work.

I want to know whether I need to have a seperate STUN server,but Openfire has provide STUN server already.

If I do not need have a seperate STUN server,how should I configure my STUN server?

Best regards.

i thin we have got the same probleme.
