TeamViewer is a remote device access program. It is specially designed for ease of use and operation, so no access to TCP or UDP ports is required to use it. This resource shows the ports used by TeamViewer and explains how you can block these ports on your laptop’s network.
Ports Used By TeamViewer
Go to the menu, then select Configuration. Then select the online protection function. The Application Rules link may appear in the next window; get there. You should now be able to access the firewall temperature.
Ports created by TeamViewer TCP 80, TCP 443 and TCP 5938.
Allow TeamViewer Ports
You are not need to redirect ports for TeamViewer to work. In fact, it will find a way out of the network, unless it is explicitly blocked. If you have any difficulty, check if your firewall has exception rules for locations 80, 443 and 5938. Also check if you are using HTTP proxy or transparent HTTP proxies – this could intercept your connection and disrupt the operation of TeamViewer servers.
How To Block TeamViewer Ports
On the small tab to the left of the very last window, select an option to navigate to Firewall and Network Protection. Scroll down and you will see the “Allow application through firewall” option. In this window, you can also check the status and set up your environment His firewall.
If you are using TeamViewer If you want to block securely on your network, there are several ways to do this:
- Block access to DNS records
- Block access to the TeamViewer IP range
- Block outbound access to TCP port 5938 on your router / firewall
- Restrict TeamViewer EXE execution using Group Policy
- Deep packet inspection in the firewall
I will receive written instructions on how to block TeamViewer ports in your Connect and in other ways. Read the instructions here.
I also wrote an article comparing TeamViewer with different remote access methods. Read the program here.
Block the TeamViewer port TeamViewer connects via plugin 5938 as well as tunnels via ports 50 (HTTP) and 443 (SSL), although 5938 is not available. To block such things, you need to go into your right firewall or router and add the best new outbound firewall rule to kill TCP and UDP ports 5938 from all original IPs.
TeamViewer does not require any configuration or even special firewall rules to establish a connection. All a dieter needs to do is buy EXE files from the website Launch them – this makes it easier for everyone to launch the game and allows you to bypass security restrictions.
