Also seems very unreliable as someone can just try older versions until they hit one that works. What is the best practice solution to this? I have searched the forums and there seems to be no definite solution. Remote desktop access solutions by TeamViewer: connect to remote computers, provide remote support & collaborate online Free for personal use +1 8. Even then the application still works. Even making the DNS resolve to nothing in the host file does nothing, it still works. So then I thought about blocking the executable name, but if someone renames their executable won't this just circumvent it easily? Looking deeper I got into file fingerprints for Application and Device Control, and that seems to be a lackluster solution as once it gets any updates at all, the hash will obviously change and I'll have to manage it again. I decided to go hardcore and block all ports for. Obviously I can't block those ports as other applications use them. I have tried blocking the TCP port 5389 (listed on their site) and it seems to work at first, but then it seems to fail over to either 80 or 443 and starts working again. Of course TeamViewer adds some security by doing a pin/password check before the main server sends the IP info to both parties but you get the idea.Has anyone here successfully blocked TeamViewer? Many firewalls do behave this way, though. If your firewalls don't behave in such a friendly manner, then this won't work. Specifically, this requires the firewalls to not change the public port of an outbound packet merely because its destination has changed the firewall must reuse the same public port as long as the source of the packet hasn't changed. If the firewalls are 'P2P-friendly', this causes both firewalls (yours and the client's) to allow the traffic, thus 'punching holes' in the firewall.

The client also starts firing UDP packets at you. The client is signaled that you intend to connect and is given your IP. Your machine then begins firing UDP packets at the client. The main server then gives you the IP address of the client machine. When you hit connect your machine tells the main server its intention. The target machine (client) also has a TCP connection to the main TeamViewer Server. The machine youre trying to access will first try to connect to the TeamViewer servers via an outbound connection on port 5938, as the connection is outbound. In order to pin hole your machine (viewer) has a TCP connection back to the main TeamViewer server. This can be locked down on enterprise grade devices, but in general 90% of the firewalls out there will allow return traffic. If they see an inbound packet that matches an outbound packet they will generally allow the packet through even without a specific rule being placed in the firewall's access list. Firewalls are designed to look for UDP packets and record the source and destination as well as the timestamp.

This means packets are fired off at their target with no verification (at the protocol level) that they were received or even reached the destination. The connection speed over this port is slower and less reliable than ports. As the private key never leaves the client computer, this procedure ensures that interconnected computersincluding the. This technology is used in a comparable form for https/SSL and is considered completely safe by today’s standards. To elaborate on ewanm89's post, TeamViewer does use UDP pinholeing. If TeamViewer cant connect over port 5938 or 443, then it will try on TCP port 80. TeamViewer traffic is secured using RSA public/private key exchange and AES (256-bit) session encryption.
