Firewall Blocks Steam

Mig-A7

Hi,

So i can't log in on Steam with the Firewall activated, Steam can't connect to their network.

Thanks,

Hi. Try to white list these ports onto the firewall.

Steam Client

UDP 27000 to 27015 inclusive (Game client traffic)

UDP 27015 to 27030 inclusive (Typically Matchmaking and HLTV)

TCP 27014 to 27050 inclusive (Steam downloads)

UDP 27031 and 27036 (incoming, for In-Home Streaming)

TCP 27036 and 27037 (incoming, for In-Home Streaming)

UDP 4380
