SMTP relay

Hi Russell,

I am guessing that you want to restrict them by IP Address or Subnet? You could use a matchclass if you are using BIG-IP v9.x.x or earlier class match if you are using v10.0.0 or later.

You simply create an iRule Datagroup and allow or deny based on the contents of the Datagroup.

Example:

when CLIENT_ACCEPTED {
   if { [class match [IP::client_addr] equals allowednetworks] } {
       pool matching.pool.name
   }
}

Hope this helps.
