Restrict access to VIP by source IP address

Afternoon,

 

 

I want to restrict access to a vip to only certain IP addresses, I have done that with the following iRule ( I took it from this forum)

 

 

when HTTP_REQUEST {

 

if { [IP::client_addr] eq "192.168.0.30" || [IP::client_addr] eq "192.168.3.10" || [IP::client_addr] eq "192.168.4.13" || [IP::client_addr] eq "192.168.5.16" } {

 

pool testapps2s

 

} else {

 

HTTP::respond 200 content "Not AllowedYou are not allowed to access this site!"

 

}

 

}

 

 

I want to add 3 different subnets to the above IPs (say 192.168.7.0, 192.168.9.0 and 102.168.12.0). How would I accomodate that in the iRule - I am a novice when it comes to this so any help would be appreciated.

 

 

Thanks
