Do I Need a Modem for Extra Security? - Page 2

post #11 of 13
Not sure if this is any use since this post is already a bit old. But as stated above, a router can include additional security in some cases.

A router will improve your security as most routers have a NAT, most modems today also have a built in router and therefore a NAT. Another point to consider is that a lot of routers include flood protection, not that it is that useful against a decent dos attack. If you don't host any servers I HIGHLY SUGGEST blocking all incoming connections on Windows Firewall, this is what a NAT does by default on most routers, blocks all ports until specified otherwise.

Bit of quick firewall info to answer your Q smile.gif

Firewalls are now known as 'statefull' firewalls, routers are infact firewalls, they are just less powerfull in theory, so when i say firewall you can replace with router smile.gif


Most home users firewalls are configurered to : allow all out, allow all back if there is an open two way conection, deny all in

So when you play games, you client (a) goes the game server, (b) starts a connection, the router sees this, and creates a rules saying allow all traffic between a <-> b. Allthough its open, only the game server sees it as open, which is how games can dynamicly make you the host of a server


If you staticlly forward ports, it opens it up to the world, something that most users dont really want to do nor need smile.gif
