Physical installation is as easy as 1-2-3. Connect the WAN and LAN ports as well as the wall power supply, flip the On / Off switch (a bad omission from many other devices) and that's it. The port indicator LEDs will show which ports are linked.

Configuration

It all goes by numbers: Open you browser and type in 192.168.0.1 to establish the connection to the ISB. The manual is very intuitive and there is hardly anything that can go wrong. I configured the ISB Pro800turbo offline through a dummy computer before substituting it for the existing firewall and the entire switch-over was done in less than 5 min.

This is the install shield that pops up as soon as the 192 ... IP address has been entered into the navigation line of the browser.

Performance

I am really not set up to measure performance of any router by hammering the router with multiple simultaneous requests so I cannot comment too much on transfer rates. For any small LAN, the file transfer rates are limited more by the I/O latencies of the storage devices than anything else. That is, copying a 50 MB file from one computer to the other inside the LAN took the same 12 seconds it took with any other router. What was very impressive, though, was the absolutely lag-less access of the browser interface for configuration. In some cases, I have been sitting and waiting for 10-30 seconds for the browser window to open whereas with the ISB Pro800turbo the screen was instantaneously there with pressing the Enter key.

Firewall Performance

We put the Firewall up against Steve Gibbon's Shields-Up online test, which was passed with flying colors. In terms of speeding up internet access, there was a noticeable difference between the DLink DI-714 and the ISB Pro800turbo in that webpages open much faster. Keep in mind that this is a subjective statement and that there are no hard data to back up these claims. Using WSFTP, the system shows a higher initial latency until the connection is established. However, once the connection is up and running, things go, once again, much faster than with the older firewall. A side effect is that time-outs that were common with the DLink device have not occurred over a limited testing period of some five days so far.
