OCS and federation

Hello,

 

First post on this forum so be gentle.

 

I currently have OCS working wonderfully, audio and video and all the goodies.

 

I am not the OCS admin so I hope I can fix this particular issue on the F5 exclusively.

 

I have the F5 LTM 1500 platform running 9.4.5, my problem is in session persistence to a machine making an outbound connection.

 

I have a couple of servers using the BIGIP as the gateway with a virtual server type forwarding(IP), these servers are also part of a standard virtual server.

 

The VIP on the virtual server is also used for SNAT on the virtual server using the forwarding.

 

When one of the server needs to set up federation to a remote server out on the internet,the remote server has to create a completely different session to the same pool server that originated that session on the standard VIP.

 

This breaks because there is no persistence option on the forwarding(IP), so the server out on the internet needs to connect to the same server that initiated that connection, which is not always the same based on my load balancing method, and it somehow breaks federation.

 

Anyway, I hope this makes sense, all I am looking for is some sort of persistence option that will take the initial connection and use it when that same combination of nodes (src/dst ip) is communicating, use the same pool member.

 

BTW, if I have an active/passive set up this appears to work just fine, obviously since the server is always the same.
