Hi Aaron,

 

 

I find that I can go around it by creating topology record "CGNO" from the GUI [Global Traffic ›› Topology : Regions] and add all IPs to it. Then I use the "matchregion" in my irule as the following:

 

 

when DNS_REQUEST {

 

if { [matchregion ldns CGNO]}{

 

host 1.1.1.1

 

log local2. "**** Request from [IP::client_addr]****"

 

 

}

 

else { host 2.2.2.2

 

log local2. "****Request from [IP::client_addr] ****"

 

}

 

}

 

 

I think using the "matchregion" in this example makes it easier to me and to my operation team to update subnets without touching the IRule.

Thanks
