Maintenace page for a subnet

I have a need to create a maintenance/apology page for a data centre shutdown. Supposing everything is on subnet 1.1.1.0/24 how would I set up a redirect to an external web site http://www.sorry.com ? I know I could use an irule for the redirect something like

 

when HTTP_REQUEST { HTTP::redirect "http://www.sorry.com" }

 

But what kind of server would I set up to apply the iRule to? If a Standard one would it need a pool to work.

 

The examples of iRules dont make it clear, what server config is needed even for a maintenance of one service. Sorry but I'm being dumb I know.

 

APM
application delivery
availability
devops
iRules
maintenance page
security

    Hi Tom,

     

    if you are using an iRule with a default redirect for ALL requests, then you don't need to specify a default pool. And to be able to use iRules with a redirect you need a Standard VS with a http-profile assigned.

     

    But I didn't understand your subnet-question. And if the whole data center is down, I would expect, that your BIG-IP is also not available anymore.

     

    Can you explain this in more detail?

     

    Ciao Stefan :)

    Hi Stefan Ok we run virtual servers on say 2 subnets and it is just those that will be down so the requirement is to catch all traffic to servers on these subnets and redirect to an offsite apology/maintenance page.

     

    I would like to be able to test this prior to the day by setting it up for,say, 1.1.1.0/30 thereby redirecting 1.1.1.1 and 1.1.1.2 to the apology (assuming I've got the mask right)
