IIRC I simply copied that from the ICE spec. So either we need to ask on 
the MMUSIC list or find some people on this list who know more about 
STUN than I do. I've also forwarded this to the [EMAIL PROTECTED] list 
(which we're using for focused discussion about Jingle -- I'll subscribe 
you to that list using my special admin powers :).

 My question was actual in the xep-0176 section 5.5 Connectivity
 Checks.

 The initiator and responder and behind NAT. We are not able to do get
 implementation right. The responder do not get the first request same
 as initiator ( illustrated   by From 192.0.2.3:45665 to

Bad reply, re-post it to standards@xmpp.org
 
Maybe your client is broken in replying (you replied to

This is more of a question for your network/firewall administrator, not
for XMPP people. For the XMPP part, refer to *XEP-0176: Jingle ICE-UDP
Transport Method*

You should generally avoid it.

I believe it's answered in (1).

Hi.

Can I have more clarity on these:

We are implementing jingle and all is going all but the configuration
NAT/Firewall for both peer is not working. I'm thinking to use relayed
candidate but I know that there is a way of punching hole in Nat/Firewall. 

1) Is it the possible to use the UDP firewall punching hole technique of
waiting the NAT to map the inbound and outbound IP to allow comunication

2) when should we use relay candidate in jingle negotiation.  

3) how with jingle can we get a usable pair of candidates behind firewall
and NAT.
