The only port you need to have exposed to the world is the +hostport (aka -port aka +port). This is the default 27015 UDP port. Add the rcon and netcon ports as you need them. The other ports need to be allocated (unless you can disable them like the hltv port), but are only used for outbound communication (or not used at all), so they don't need to be open inbound on your firewall.

As it stands right now, we have the following ports open to each of our game server IPs: TCP 27015 UDP 1200 UDP 27000-27015 Let's say I start a server using the following command line: ./srcds_run \ -game left4dead \ -ip x.x.x.x \ -nohltv \ +map l4d_dem_hospital01_apartment\ -fork 8 This should start 8 servers, and since I'm not using hltv, they should be listening on sequential UDP ports 27015-27022. In this case I would simply ask to have UDP ports 27016-27022 opened up. However, in Milton's e-mail he mentioned other options, such as -steamport, +clientport +hostport, +matchmakingport, and +systemlinkport. Would any of these ports need to be specified as well?
