Which port(s) do you want clients to connect to the VIP(s) on? Typically, you'd have an HTTP VIP running on port 80 and an HTTPS VIP running on port 443. And then which port(s) do you want LTM to send requests to the pool member(s) on for each VIP? The VIP port and client/server side SSL configuration is independent of the pool member(s) port(s). If you enable port translation on the VIP, LTM will translate the destination port when establishing a connection to the pool members to the port the pool member is defined on. LTM will decrypt SSL on the clientside connection if you add a client SSL profile to the VIP.
