Hi BB1030,

 

For influencing the result based on source IP, try following rule

 

 

 

rule "SourceIP-rule" {

 

when DNS_REQUEST {

 

if { [IP::addr [IP::client_addr] equals 10.x.x.x/24] \

 

or [IP::addr [IP::client_addr] equals 11.x.x.x/24] } {

 

cname "host.something.com""

 

}

 

}

 

}

 

 

in place of cname you can write any action you want, list can be found @ https://devcentral.f5.com/wiki/iRules.GTM.ashx

 

 

Cheers
