pool selection based on client ip

I'd like to see the data group that's associated with your rule.

I think your first attempt was closer, as you were using the client_addr variable.

Try something like:

when RULE_INIT {
  log local0. "qa-rule --BRAD"
}
when CLIENT_ACCEPTED {
  if { [ matchclass [IP::client_addr] equals $::test ] > 0 } {
    pool qa-01-101-7200
  } else {
    drop
  }
}

But yes, things look fine in general, and that rule should allow you to select a pool based on the IP.
