Hello Daniel,


that was it. I was calling fix_nated_contact in LB but also in

Hello,

very likely you use fix natted contact in reg+proxy. You have to use that in
load balancer, since that is the instance that sees the right public ip
address for UA. reg+proxy will see IP address of LB as being source IP
address.

Cheers,
Daniel

Hello list,

let me first show my scenario:

UAC_A  --->    LB --->    |
                    | PROXY+REG #1
                    |      or
                    | PROXY+REG #2
UAC_B<--- LB<--- |

Could you please repeat the trace but in a easier format:

   ngrep -d eth0 -W byline -T port 5060
