Hi,
I seem to have a problem replies to PRACKs from NATed UAs. The UA is
behind the NAT on a private IP listening on port 5060. This port gets
mapped to 1350 on the external IP by the NAT device.
The INVITE goes out fine and gets the contact updated for NAT by:
if (client_nat_test("3")) {
setflag(7);
force_rport();
fix_contact();
};
This then receives a 183 reply to which it sends a PRACK. However, the
200 response to the PRACK gets sent to port 5060 on the external IP =>
which of course doesn't get to the UA.
Is there something I'm missing in my config? I have attached a trace of
the call setup.
Jeff

Hi Jeff,
You will need to force the rport for the ACK.
Compare the Via header in the INVITE against the Via header in PRACK.
Hope this helps,

Hi,
I seem to have a problem replies to PRACKs from NATed UAs. The UA is
behind the NAT on a private IP listening on port 5060. This port gets
mapped to 1350 on the external IP by the NAT device.
The INVITE goes out fine and gets the contact updated for NAT by:
if (client_nat_test("3")) {
setflag(7);
force_rport();
fix_contact();
};
This then receives a 183 reply to which it sends a PRACK. However, the
200 response to the PRACK gets sent to port 5060 on the external IP =>
which of course doesn't get to the UA.
Is there something I'm missing in my config? I have attached a trace of
the call setup.

I'm having this same situation.... 2 clients behind the same NAT with
diferent port on reponse...
The tip is good, I get the logic, but I can't find an example on how to get
VIA's informations... Could someone help me?
Edson.

Hi Jeff,
You will need to force the rport for the ACK.
Compare the Via header in the INVITE against the Via header in PRACK.
Thank you,
This fixed the issue.
Jeff

Hi Edson,
you do not need to manually inspect VIA - just use force_rport() and the
function will do all the job for you.
