F5 is a default deny device so unless you explicitly allow it, any flow between directly connected VLANs will not pass through.

 

In your forward VS settings, make sure you didn't allow it to listen on all VLANs. For this, you need to set the "VLAN and Tunnel Traffic" parameter to Enabled on your external vlan only.
