iRule help to allow 2 ip's only

Create an IP datagroup containing the IPs you want to allow, then try this...

    when CLIENT_ACCEPTED {
           set yesno [class match [IP::client_addr] equals "allowed_ip"]
           switch $yesno {
                          "" { discard }
                          default { log local0. "Accepted client from [IP::client_addr" }
           }
    }
