Redirect to DMZ instead to Internet for a specific website

OK, thanks. The iRule won't work if the Virtual Server type is anything other than Standard, which I suspect yours is not, it'll also require a HTTP Profile to be assigned.

 

 

You have a couple of options I think;

 

1) Change your internal DNS (assuming it's separate to the external) to point to a new Virtual Server with some sort of valid internal address, that points to the DMZ servers

 

2) Create a separate Virtual Server using the public IP, enable it only on the user VLAN, assign your pool of DMZ servers. I know this sounds like it won't but it will work. VS IPs do not need to be tied to Self IPs/physical interfaces in any way, as long as the client requests are routed to the F5 (rather than the client ARPing).
