Steam Server Names for Firewall configuration

[76561198864525724]

Hey there, which server names (or better, IPs/IP ranges, protocols) do i need to open (for a company firewall request) for being able to update steam/steamvr and general access?

I'll list some necessary ports, domains and what not.

To log into Steam and download content (Steam's CDN)

:

• HTTP (TCP port 80) and HTTPS (443)

• UDP 27015 through 27030

• TCP 27015 through 27030

Steam Client

———————————————————————————————————————————

• UDP 27000 to 27015 inclusive [Game client traffic]

• UDP 27015 to 27030 inclusive [Typically Matchmaking and HLTV]
  • UDP 27031 and 27036 [incoming, for In-Home Streaming]
  • TCP 27036 and 27037 [incoming, for In-Home Streaming]
  • UDP 4380
  ———————————————————————————————————————————

  Dedicated or Listen Servers

  • TCP 27015 (SRCDS Rcon port)
    
    

    Steamworks P2P Networking and Steam Voice Chat

    
    
    • UDP 3478 (Outbound)
    • UDP 4379 (Outbound)
    • UDP 4380 (Outbound)
    
    ———————————————————————————————————————————
    
    

    Note:
    
    Many university networks and proxies block required ports for Steam operation - please consult your network administrator to ensure the required ports are open if you are using a university network or a proxy. Ports required for Steam can not be re-mapped to HTTP or reconfigured to a custom port range.

    Advanced

    
    For generic Steam HTTP/HTTPS requests, your proxy / fire-wall should allow the following domains:
    
    
    • steampowered.com
    • steamcommunity.com
    • steamgames.com
    • steamusercontent.com
    • steamcontent.com
    • steamstatic.com
    • akamaihd.net
    
    Most of the non-web traffic is usually UDP but can be TCP as well. For that, the IPs will all be from the Valve network (AS32590), and a list of those IP blocks can be found here:
    
    
    • IPv4[bgp.he.net]
    • IPv6[bgp.he.net]
    
    ———————————————————————————————————————————
    
    
    

    Now, for the executables that your fire-wall should allow

    
    

    Open the configuration view for your firewall program, and remove any instances of the following executable from the permissions:

    
    
    • steaminstall.exe
    • steam.exe
    • hl.exe
    • hl2.exe
    • steamTmp.exe
