[SR-Users] Kamailio ims nat issue: PRACK/ACK ruri changing in p-cscf

Hi all, 
My scenario is as follows: 
I have All the CSCFs on the same IP using different ports. 
P-CSCF advertises a public IP. Rest of the nodes including I-CSCF and S-CSCF
listen local only. 

Behavior: When an ACK or PRACK goes from P-CSCF to S-CSCF, the RURI changes
such that alias parameter is removed. 
Hence, P-CSCF ends up sending PRACK and ACK on private IP of UE. 

Here's what the config looks like:

#!define WITH_NAT

Any hints?
