How to allow both HTTP and HTTPS traffic from a single VIP?

I'd recommend two Virtual Servers instead - one for port TCP 80, another for port TCP 443. It's a straight-forward setup which is a much preferred configuration over a wildcard Virtual Server. It's not a bad idea to go for a wildcard VS if the number of ports is significant (i.e. a few hundred), but I see no good reason for a single VS setup if you're just working with two ports (80 and 443).

If you insist on using a single VS for whatever reason, just configure it as L4 Performance (or Standard) Type Virtual Server with port number set to *. Do not apply HTTP profile. Now the main question is, if you accept clientside TCP port 80 connections, do you want the serverside connections to be routed to Pool-Member:443, or Pool-Member:80? Depending on your requirements, you may need to use an iRule (CLIENT_ACCEPTED event) or LTM Local Trafic Policy to select the appropriate destination.

As you set VS port number to * (any), you also want to make sure you do not allow incoming requests to other ports besides TCP 80 and 443. For that, you must fine-tune the pool-selection Policy/iRule to drop packets to irrelevant ports. Luckily, that's not very hard to do either. Just let us know if you need help with anything.
