Some questions about jingle

Hi all,

I encontered a very serious problem, here is:

I put two JingleDemo clients in two different LANS, and the openfire3.3.2 server put in the

internet which has two public IPs, the two clients can’t call to earch other. Both the LANS behind in

a NAT device–port restricted cone NAT, I have set the openfire with two public IPs, the media proxy

and the stun service both have been set and started, so can you tell me how l can do it successfully?
