AltocumulusSo i've setup a split DNS iRule however for some reason, the client IP is not being matched to the IP entries in my datagroup. I've created two datagroups to see if the name was an issue but that didnt resolve the problem. If i switch the configuration to a known working datagroup, split DNS works perfectly. Any ideas? pulling my hair out.
Could you share you iRule and datagroup configuration?

when DNS_REQUEST {
if { [class match [IP::client_addr] equals datagroupname] } {
pool practice-dnspool
}
}Lets try basic troubleshooting...
when DNS_REQUEST {
log local0. "I'm receiving a new dns request and my client IP is [IP::client_addr]"
if { [class match [IP::client_addr] equals datagroupname] } {
log local0. "I'm inside and my client IP is [IP::client_addr]"
pool practice-dnspool
}
}If no messages are shown in the second step, you should check the datagroup structure. Share this command output.
