When IP:port1 and IP:port2, the identifier is different for LVS, and I
will see 2 connections in ipvsadm

For me, it is good if I have a lot of client, like this configuration :
client1 |
...........|--------------director ---------realserver 1 to n
clientn |
In this case, it will work fine for me, because I use SIP proxy or
something very similar.
But, one case is used when we create a IMS/SIP network :
client1 --- clientn
...........|
IMS box which will receive call, but forward them in one udp socket
(or one tcp socket)
...........|
director (only one connection in basic setup so)
...........|
-----------------------------------
realserver1...............realservern
In this case, I will not loadbalance correctly.
So, It's my turn to work ;)
PS : when I was searching, I found some references to a SIP adaptation
for LVS. I know it's not complete, but can someone link me to the last
version ?
Thanks for your help,
