    We have this resolved. Initially it was necessary to add the new vlans to the port channels used for the f5 to communicate with the balance of the application infrastructure. Once this was accomplished and irule to limit the VS to the specific ports required for application delivery was applied and finally to insure IP persistence through the entire data flow for the application the default gateway for the application servers had to be set to the float ip for the VLAN on the application servers, routing return traffic back through the BigIP.

This can be due to multiple reasons. If no SNAT option applied, does your servers has route back to the client subnet? If the VIP and the servers's ip on the same subnet then SNAT/Automap need to be configured. Does your server allows connection from client IP or SNAT/Self IP?

 

Can you provide VIP config? The packet capture can help much
