restricting urls for a virtual server

Hi, I have below setup Internet user --> Internet Firewall --> F5 --> Backend server (Pool Member)

 

I have created a virtual server on F5 with IP address 10.10.10.10 which is nattted on internet firewall with 98.98.98.98 IP address. I want this webserver to accept only connections coming for test1.abc.com and test2.abc.com, if test3.abc.com lands on this virtual server then it should be discarded.

    Hi Nuriddin,

     

    You can use irule shown below.

     

    when HTTP_REQUEST {

     

    if {([string tolower [HTTP::host]] equals ";) || ([string tolower [HTTP::host]] equals ";)}{

     

    pool webpool

     

    }

     

    else {

     

    reject

     

    }

     

    }

    You can also use the datagroup/class:

    when HTTP_REQUEST {
if { not ([class match [HTTP::host] equals ALLOWED_DOMAINS]) } {
reject
}
}

    ALLOWED_DOMAINS is a datagroup that contains the list of domains that can be allowed.
