I have filled in the information based on my loose understanding of how Steam works, but some information is totally bogus (i.e. Just so there is no confusion, here is an example of what I am proposing. Is it possible to re-structure the support page to make these requirements a little more clear? Which traffic is required to be passed in the outbound (local -> internet) direction? Which traffic is required to be port-forwarded in the inbound (internet -> local) direction? So.my question: Given the uncertainty above, is it possible to get some clarification around the following: Further, I suspect that UDP 4380 should also be forwarded based on my loose understanding of Steam P2P networking. In the inbound direction, it would seem that UDP 27031:27036 and TCP 27036:27037 may need to be forwarded to a specific host if in-home streaming is needed. In the outbound direction, it would seem that UDP 3478, 43, as well as UDP 27000:27030 and TCP 27014:27050 simply need to be permitted (passed) in the outbound direction, rather than port forwarded. Based on other reading that I have done to get AoEII:HD working, it seems that UDP 4380 should be permitted in the outbound direction and redirected (forwarded) in the inbound direction because it is used for P2P networking. UDP 4380 is actually listed twice, so it is unclear in which direction it should be passed and/or forwarded.

TCP 27014 to 27050 inclusive (Steam downloads) UDP 27015 to 27030 inclusive (Typically Matchmaking and HLTV) UDP 27000 to 27015 inclusive (Game client traffic) There is no indication as to whether the following traffic should be permitted in the 'inbound' or 'outbound' direction: TCP 2707 (incoming, for In-Home Streaming) UDP 2706 (incoming, for In-Home Streaming) The following traffic is shown as requiring 'incoming' access: For example, the following traffic is shown as requiring 'outbound' access (where 'outbound' means traffic originating from the Steam client and bound for the internet): The port forwarding guide seems to blur the lines between two distinct topics - port forwarding and firewalling. Steam support have asked me to re-post the information here. I have had some dialogue with Steam support about the 'Required Ports for Steam' guide at.
