Thread: Protect your router

Even if it sounds funny: When you DSL users is never directly connected to the Internet. This is due to the router that stands between your computer and any threat from the Internet. Thanks to the so-called NAT (Network Address Translation) to use when surfing always two different IP addresses, the router receives when dialing a public IP address from the access provider. All devices on your network behind the router, however, have a private IP address, typically "192.168.000.001".


Requires a PC to a website, this is NAT on with the public IP address to the Internet. NAT receives the page and then forwards it to the private address of PCs on the local network. NAT so constantly exchanged private IP addresses to




public and vice versa. With the success that the IP address of PCs on the Internet does not appear, which makes him immune to direct attacks. In addition, the router discards incoming data packets that were not requested.


To this fundamental protection, you need not worry. You can be in the router's configuration to reduce optional, but not increase. Some measures but remain active: Do not forget to update the duty of the device software on the router. They conclude that any gaps in security.


Change the default factory configuration for the 08/15-Passwort interface of the router, otherwise attackers could latch. Newer devices already offer individual passwords.

The network protocol "Universal Plug and Play" allows devices to change the router configuration and theoretically reduce the security. Turning off the router but impunity is possible only for very simple network claims: messenger, peer-to-peer networks, media servers and network printers require UPnP.
