What is difference between object-group protocol and object-group service when the object points at port ?

Hi Expert,  Sometimes, Object-group protocol and object-group service have very similar function. do you think so ? Or what is difference between both of them ? Thank you

For example:

P3/pri/act(config-protocol)# protocol-object pptp

P3/pri/act(config-service)# port-object eq pptp

  igmp    
  igrp    
  ip      
  ipinip

  pptp    
  snp

It would seem you can? strange that the protocol actually needed for ppt is GRE and thats listed separately! (protocol 47)

Ah its just a placeholder pptt and gre both open Protocol 47 see the table here http://www.cisco.com/c/en/us/td/docs/security/asa/asa82/configuration/guide/config/ref_ports.html#wpxref39421

Opening the PPTP via the port config simply identifies TCP port 1723  - so that are not the same :)

What PeteLong said.

Protocol is for protocols:  tcp, udp, gre, esp, etc.

Services are for ports: 1-65535
