Re: [Ekiga-list] STUN registration

[Wolfram Wagner <Wolfram Wagner web de>]

Hello Damien, 

Thanks for your reply. It took a while until I had time again.

Please remember, I have problems with registration and get a 404 not 
found message.
 Last time you answered me, that I should sniff a bit. So I did.

I found out, that registration at STUN server is done maybe by using a 
wrong IP. My current IP is 84.159.48.129.


In STUN Registration I see contact binding:
	URI: <sip:wolfram wagner 84 159 61 31:5073;transport=udp>

Then my client sends SUBSCRIBE using the same wrong IP Address.

Next I get a 404 Error (not found) telling me 
Sent-by Address: 84.159.61.31
Sent-by port: 5074
...
RPort: 5074
Received: 84.159.48.129
...
Warning: 392 192.168.70.52:5060 "Noisy feedback tells:  pid=16986 
req_src_ip=84.159.48.129 req_src_port=5074 
in_uri=sip:wolfram wagner ekiga net 
out_uri=sip:wolfram wagner ekiga net via_cnt==1"


So I wonder where this IP 84.159.61.31 comes from. I checked it and it 
is one of the dynamic addresses used by my provider. The check via 
ekiga.net/ip returnes the correct ip.

After three more Register retries it gives up.


Might it be possible that this wrong ip address makes problems in 
registration. Maybe the answer packages are sent to this machine.

Thanks and Have a very nice Christmas!

The 404 is for the SUBSCRIBE (it is a normal behavior). The timeout is
for the REGISTER.

That means that :
- the SUBSCRIBE reaches ekiga.net
- the REGISTER, which is identical, doesn't reach ekiga.net OR the reply
to the REGISTER doesn't reach your internal host

Can you sniff the traffic on the routers to see what happens?

I have the feeling that one of them is either dropping the REGISTER, or
dropping the answer to the REGISTER or simply rewriting the REGISTER in
such a way that the answer never reaches you...
