F5 Lync iApp with Cisco firewalls

I have configured the Lync iApp on a F5 LTM in our DMZ behind a Cisco firewall.

 

The client AV traffic goes through the firewall, hits the F5, which sends it on to one of the edge servers (in the same network as the F5) but when the edge server then replies direct to the client the firewal drops the packet as it hasnt seen a SYN packet from the client to the edge (the original SYN went from the client to the F5).

 

Am I configuring something wrong here, shouldnt the F5 tell the client to re-connect to the edge directly?

 

Any help appreciated.

 

Thanks

 

Richard
