[lvs-users] LVS 4 SIP setup help needed

[Ashi Aber]

Hi,
Below is the setup I'm testing.
Need to balance SIP from a single source to two clustered servers.
Both servers listen on SIP ports 5060 and 5065.
Each server serves as master for its VIP and backup for the other servers VIP.
The IP VIP stuff works fine.
The SIP traffic doesn’t balance evenly and doesn’t failback (when I fail one of the ports, the traffic is redirected to the other server, but, when I restore the service the traffic doesn’t move back).

Not sure what are the best settings for this layout....
