Hello list,
let me first show my scenario:
UAC_A ---> LB ---> | | PROXY+REG #1 | or | PROXY+REG #2 UAC_B <--- LB <--- |
LB cfg: modparam("path", "use_received", 1)
loose_route(); #for REG+PROXY
if(is_method("REGISTER")){ add_path_received(); ds_select_dst("1", "0"); fix_nated_register(); } else { record_route(); add_path(); ds_select_dst("1", "0"); fix_nated_register(); }
PROXY+REG cfg: ------------- modparam("registrar", "use_path", 1) modparam("registrar", "path_mode", 0) modparam("registrar", "path_use_received", 1)
INVITE if working fine until ACK. UAC_A sends ACK to LB "ACK sip:UAC_B@LB_IP:5678;" insted of "ACK sip:UAC_B@UAC_B_PUB_IP:". In "200 OK" which PROXY sends to LB Contact is rewritten with ip addres of LB "Contact: <sip:UAC_B@LB_IP:5678;" and this is why UAC_A sends wrong ACK. Obviously I miss something so if someone could point me where to look.
Thanks
Pavel

let me first show my scenario:

Could you please repeat the trace but in a easier format:
ngrep -d eth0 -W byline -T port 5060

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
-- Iñaki Baz Castillo ibc@aliax.net
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

Hello Daniel,
that was it. I was calling fix_nated_contact in LB but also in onreply_route in REG+PROXY.
Thank you very much!

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 Daniel,
that was it. I was calling fix_nated_contact in LB but also in onreply_route in REG+PROXY.
Thank you very much!
great you fixed, welcome!

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
