CSS to F5 migration question ( with multiple VLAN's)

Thanks for the response. What i meant on my 2nd question was that my set is something like Internnet router --> Internet Switch ---> Firewall ---> Server Switch ---> Servers & LTM ( both connected to this switch)

so my question is that should i create 2 trunks from LTM towards the connected Server switch or just create one trunk and pass both External and Internal VLAN in it. I don't see a big differentiation in external Vs Internal Vlan. The external vlan is a /28 subnet which has the Fwall inside port, Server Switch. The internal vlan is the subnet in which i have the Physcial Servers, Server Switch connected to it . Since the route for the F5 to either Internet or to Inside Servers is through that same server switch, i'm confused as to where i can just build a trunk from LTM to Server Switch and pass all VLAN's. ( Also, i'm confused on the concept of internal Vs External VLAN in this scenario)..

Thanks in Advance ..
