Firewall Problem Detected

The Warframe network analysis tool detected a problem with your network; this could be the root cause of contact list, matchmaking and even voice-communication issues. Since Warframe is much more fun with friends we want to help you sort out your network troubles and get you back in the game!




Warframe uses UDP ports 4950 and 4955 & the TCP port range 6695 - 6699. Your firewall needs to let traffic on those ports from any address through to your PC (and from these ports on your PC to any address).

Firewalls are an important part of a network’s security; their job is to prevent unauthorized network traffic from passing through (ie: malicious hackers or viruses trying to connect to your PC). A conservative firewall can be configured to block most traffic and require administrators to grant exceptions to specific programs to allow their traffic through.

There are often several firewalls involved in a network: many PCs have a personal firewall software package built-in (for example: Microsoft Windows Firewall, Norton Internet Security, and ZoneAlarm), and many home routers have a firewall as well.

To solve this problem you have to figure out which firewall is blocking Warframe’s network traffic. The easiest way to identify the culprit is to temporarily disable each firewall and then re-running the Warframe network analysis tool until it succeeds.

Once you have identified which firewall is blocking the traffic you can re-enable the firewall, create an exception for Warframe and test again to make sure it is working.
