I need to create a site to site vpn tunnel and was told that its not a good idea to specify the tcp ports on the associated acl. The reason had something to do with the stability or reliability of the tunnel. From a security standpoint, I would think that having the ports would be better. what's the best way to go?
thanks, let me ask the question a different way, if its the interesting traffic that needs the tcp port, does that make a difference? Or, for the interesting traffic, is it still recommended to not use the tcp port?
