[Users] problem with OpenSER + Asterisk + F5 load-balancing switch

26 Feb 2006

Hi,

I'm having a problem trying to set up OpenSER + Asterisk + F5 
load-balancing switch.  Establishing the call (w/ no audio) seems to 
work alright but when the client hangs up, the OK reply from Asterisk 
never reaches the client.  By the way, I'll get to the audio problem 
after the SIP problem is solved.

Here's my setup:
1)  2 OpenSER boxes behind NAT with 198.168.2.X IPs and a public virtual 
IP X.X.X.X.
2)  2 Asterisk boxes behind NAT with 192.168.3.X IPs and a public 
virtual IP Y.Y.Y.Y.
3)  2 MySQL database boxes behind NAT with 192.168.4.X IPs and a private 
virtual IP 192.168.4.10.

Each set of boxes are in it's on VLAN so the gateways are .1 for each 
subnet.

Attached are the logs from the private and public interfaces on the F5 
switch.

Can someone tell me what I'm doing wrong?  or if my setup needs to be 
changed?  Thanks in advance.

Jack
