[QUOTE=Moonlighter;323573]For connection issues, try the following:
- Forward UDP ports 27015 - 27016 and 8766 to your computer’s IP address. (May need to ensure your computer is set up with a static IP address in the router’s DHCP configuration).
- Update your router’s firmware.
- Disable any router Firewall settings.
- Disable IP Flood Protection in your router.
- If using a seperate router and modem, try connecting your computer directly to the modem. (If it works connected directly to your modem, the problem lies with the router).
For help with any of this for your brand router, you’ll need to refer either to your user’s manual, or the manufacturer’s web site.
If you still have issues, or you’ve determined via step 5 that the problem lies with the router, please post your router’s make and model so we can determine any trends in terms of a particular brand or model. Also list any traffic monitoring or limiting software you may have on your computer (such as a software firewall or IP blocker)[/QUOTE]
This issue is definitely not a router issue! At least if you dont have a creepy router firewall enabled. In my case it isn’t and the Windows Firewall is working properly so there must be another root of the cause. Steam can also fully access the windows firewall and as I said before, before the latest patch the game had not this issue…
