  • Is the clients on the same vlan as well? Have you tried to simply enable automap to see if it's an issue with assymetric routing?
  • Have you made sure that the VIP listens on the external VLAN as well?

Forwarding vips should be configured to listen to packets destined for the network it's meant to forward to.

 

Example:

 

  • External network - 10.0.0.0/24
  • Internal network - 192.168.1.0/24

If you wanted the F5 to route traffic to 192.168.1.0/24 you want to create a forwarding vip with destination 192.168.1.0 and a netmask of 255.255.255.0. It should listen to the external VLAN (or all, but that would short circuit inter VLAN communications, which is not very secure).
