I should add, that what is going back to the 10.75.23.212 host is also
wrong:
14:04:53.723018 IP 10.75.23.212.6060 > 10.75.22.8.23768: UDP, length 0
14:04:53.877539 IP 10.75.22.8.5060 > 10.75.23.212.6060: SIP, length: 555
14:04:53.910351 IP 10.75.23.212.6060 > 10.75.22.8.23768: UDP, length 472
14:04:53.912158 IP 10.75.22.8.5060 > 10.75.23.212.6060: SIP, length: 555
As you can see, what is being returned is not having it's port un-
natted back to 23768. But that is perhaps unsurprising given that the
connection never gets to ASSURED.
Cheers,
b.
