Absolutely right, but for most people those "Routers" will do. They are able to stop unwanted connections to your computer but are not necessarely stateful inspection firewalls like a Cisco Pix. Also, if u install something like that u need to know what u are doing too. I have found endless routers with their web interface open on the internet. So whats the point of having a firewall if u dont know how to configure it. if u just use one computer ur best bet is a software firewall like Norton. Its still considerable easy to configure for endusers. As end user its important to protect your pc from beeing hikjacked and absued to hack other systems but in most cases u r not a target of a hacker. There are much better ways. If u run a business u might want to consider spending a few extra bux and get a Cisco Pix. Depending on the features and the size of your network there are different models. For the most small businesses a 501 will do just fine. Its got plenty of throughput, even with 3des VPN. But its is necessary to know what u configure. Also a firewall cant stop an attack to an unsecured web server. That is called intrusion detection or IDS. Firewalls actually are a complex system of different components, not just one box. Hope that helped

A simple NAT device would be a better name, but still not an "accurate" definition. Regular Network Address Translation (NAT) uses a pool of external IP addresses to randomly use for internal clients. I don't think the Linksys or SMC does that. It lets you have one external IP address. This is another type of NAT called "NAT overload" or aka Port Address Translation (PAT).
Maybe I'm just too picky on how things are marketed.  Anyway, here are my suggestions:
For ease of use on a small home network, use an SMC or Linksys "router".
For high performance on a small to medium sized network with lots of flexibility and security, go for a Cisco PIX 501 or 506. You could also consider a 806, 1605R, 2514, 2611, 2621 Router, these models each offer two fixed ethernet ports. You wouldn't get any advanced firewall features of the PIX, but the IOS firewall with access lists is alot better than a Linksys.
Any more requirements and you should look at the PIX 515, 520, and on up in combination with a regular cisco router. But who can afford this kinda stuff for home.  |
