Hi @Michael, after I put <param name="NDLB-force-rport" value="true"/> in my internal sip profile FS send back to right dst_port. If I use this on live fs server, could this be causing any problems on registered phones or any easier abuse? Thanks! Miha On 5/11/2012 8:25 AM, Miha wrote:
Hi @Michael,
thanks for your reply.
I also noticed after I send you an email that this is NAT issue. Phone send registration packet on port 5060 (src port is 50006), but FS do not reply back to port 50006 but instead reply on 5060 due to this phone does not receive 401 and and send another REGISTER packet.
How can I deal whit this issue?
Thank you very much for all your help!
p.s.: I also send you separately wireshark trace that you can see this issue.
Regards, Miha

It's definitely a NAT issue. The phone is not responding to your 401 and is instead just sending another REGISTER packet. Notice that FS is responding on port 5060. Is that the port your phone is expecting to receive on?

Hi,
here is pastebin of siptrace (http://pastebin.freeswitch.org/19029).
Phone on local network are registered on FS. After I put between local network and Phone router, phones are unable to registered on FS.
On other softswitch which is not FS phones are registering (same port, same scenario, etc.).
Phones are SPA922.
What could be causing the problem?
Thanks!
Miha
