So I'm trying to portforward the nessicary ports to get steam running through my DLink DI-604, and I can't figure out what I'm supposed to do for 'UDP 27000 to 27015 inclusive' and 'TCP 27030 to 27039 inclusive', as I can't figure out how to open multiple port ranges nor can I figure out what inclusive is supposed to mean. Any help would be much appreciated.
