The Linksys router was the only router that offered wireless capabilities. It supports both A and G wireless modes. Setting up this unit wasn't too hard, there are just a few things you have to do such as select the encapsulation, multiplexing parameters as well as enter your ADSL login credentials. It takes a few moments to establish a link, something that we didn't really find with the other units. If you look under the wireless menu you can set up WEP or WPA which uses stronger encryption.
Under the security menu you can configure the security settings of the firewall. You can filter Java Applets, Cookies, Active X objects, and Proxies. By default the router blocks anonymous Internet requests. We only found this option enabled on the Linksys which was a bit surprising. We actually had to disable this fine option because it was stopping us pinging the router from a public PC.
We encountered problems running nmap -- which in fact is a great result because it means we couldn't exploit any open ports. However, we thought this was strange so we disabled the firewall and we surprisingly we still couldn't run nmap. Unfortunately we didn't have much time to get to the bottom of this, with more time we could have possibly got it to run nmap but it most likely would've invovled tweaking the unit to make it less secure. So it really is to the device's credit we couldn't find any open ports.
The Linksys also has an integrated VPN server supporting DES and 3DES encryption. Not bad for a device that only costs AU$249. The Linksys can be setup for remote management and has some decent reporting built in. It can also e-mail security alerts.
