ISA 2004: “All IP Traffic” really means it

With ISA 2000, while “All IP Traffic” rules were open slather for Firewall clients, they actually meant “All IP Traffic For Which I Have A Protocol Definition” for SecureNAT clients.

With ISA 2004, that’s no longer the case, it really means everything, so there’s no need to create loads of definitions for each port you need to use unless you’re locking it down to specific ports or ranges.

Application Filters are still used, though.
