On a Mac.
I've forwarded ports 80 and 443 to my internal Tivo IP (airport extreme). I can access the Tivo just fine from within my firewall. However, from the outside world I can't get in.
I thought that perhaps my provider (Cablevision) blocks port 443, but there's nothing on their site about that - just ports 80 and 25 (which are open).
Any ideas, Tivo Community??
