[Spce-user] mr4.1.1 ¿Problem between LB and Proxy?

[Sergio Serrano]

I'm sorry but I can't explain well. response are correct from
12.0.0.1:5062(Proxy) and 127.0.0.1:5060(LB) but then there is no
traffic from public IP address of LB and public IP of subscriber. It's
something like this:
A.A.A.A(subscriber)  -REGISTER-> B.B.B.B.(LB)
127.0.0.1:5060(LB) -REGISTER-> 127.0.0.1:5062(PROXY)
127.0.0.1:5062(PROXY) -100 TRYING-> 127.0.0.1:5062(LB)
Here, LB doesn't send 100 TRYING to subscriber
127.0.0.1:5062(PROXY) -401 Unauthorized-> 127.0.0.1:5062(LB)
Here, LB doesn't send 401 Unauthorized to subscriber
Then subscriber resend REGISTER again
and this loop is forever. 
In kamailio-lb log I can see the message 2016-01
-28T18:23:16.178771+01:00 sbc lb[14381]: DEBUG: <core> [forward.c:835]:
do_forward_reply(): reply forwarded to A.A.A.A:5060, but LB never send
reply to subscriber.
it could be possible?
Regards
Sergio
