Floating IP --> Traffic

    would this be the Self IP of the VIP vlan or the server vlan?

    Thanks.

      Self-IP on the egress VLAN towards your pool member - if your F5 has a TMM route to it. It can even be a Management IP if you're missing TMM route to pool member IP/subnet - in that case F5 can use a route (and Src IP) from management routing table.
