Do you see an error in /var/log/ltm?

Also, you should create a class with type of Address and put the IP address(es):

class address_class_test {

host 1.2.3.4

}

Also, LB::server will return the IP address of the selected node. I assume the node is the client in the scenario you're testing now?

Can you add a log statement to see what values you're getting?


when LB_SELECTED {
   log local0. "\[LB::server\]: [LB::server], \[IP::client_addr\]: [IP::client_addr]"
   if { [matchclass [LB::server] equals $::Hosts]} {
      snat automap
   }
}
