Newbie mantenance page based on IP address

Did you create the datagroup yet? It's pretty self-explanatory once you get to the data groups section via my instructions above.

From there, let's say you made a data group called "maintenance_addresses." Your iRule would look similar to below:

when HTTP_REQUEST {
   if { ![matchclass [IP::client_addr] eq maintenance_addresses] } {
        HTTP::redirect "http://www.sample.com/maintenancepage.html" }
   }

For a step-by-step on the rule:

1. First, we're doing this from the HTTP_REQUEST event. That event is triggered as soon as the user makes an HTTP Request.

2. We're using "matchclass" to see whether the data group you created contains the user's IP address. Since we want to redirect users whose IPs aren't in the data group, we're using the "!" symbol to basically say "if their address isn't in the data group."

3. If their address wasn't in the data group, we redirect them to the maintenance page.
