    We use this which gives a complete picture of the connection from client to server:

  set client_remote "[IP::client_addr]:[TCP::client_port]"
  set client_local  "[IP::local_addr clientside]:[TCP::local_port clientside]"
  set server_local  "[IP::local_addr]:[TCP::local_port]"
  set server_remote "[IP::server_addr]:[TCP::server_port]"
  log local0. "Got connection: Client($client_remote)<->($client_local)LTM($server_local)<->($server_remote)Server"
}
