Greetings,
I have a doubt about the flag 16 used in nat_uac_test() belonging to the
module NATDETECT.
In the documentation, the following is stated :
*16* - Test if the source port is different from the port in the “Via”
header
I have some situations that I receive a request from port 5060 and the Via
Header contains no port. I think it probably assumes that it is the default
port.
Will this situation trigger the "16" flag ?
Thanks in advance,
Cheers

Hello,
I haven't tested it for you. :-)
But as I look to the code, it should then assume that its the default SIP port
5060.
nat_uac_test -> received_via_test -> check_via_address:
"if (port==0) port=SIP_PORT;"
Best regards,
Henning

This one for was for the complete address comparison, but for the port its the
same:
nathelper.c:
if((tests & NAT_UAC_TEST_RPORT) && (msg->rcv.src_port !=
(msg->via1->port ?
msg->via1->port : SIP_PORT)))
