No uplink ports
Setup and Installation
The DI-604's Setup Wizard supports dynamic or static IP address (or PPoE) assignment on its WAN port.
Features
It measures a mere 1 x 5.5 x 4.5 (HxWxD) and the case is made of metallicized plastic. The status lights reside behind a smoked plastic window, and all the ports are located on the rear.
The ports, also auto-detect 10 or 100 Mbps speeds, but they don't sense whether they are connected to a PC or another switch or hub, and there is no uplink button.
If you need to accommodate more than four clients via another device (not unlikely, even in home networks), you'll need to buy (or make) a crossover cable.
One of the most notable features of the DI-604, is content control. Also, you can schedule it to prevent access at different days or times of day.
You can schedule such features as Virtual Servers and firewall rules.
Other features, include the ability to save your router settings to a file on your hard drive, and the inclusion of a link to check for router firmware upgrades, saving you the trouble of having to peruse D-Link's site manually to look for them.
The DI-604 has the ability to log a variety of events, including attacks and dropped packets. The router can also e-mail logs to an administrator, though this feature is concealed under a button labeled "Log Settings."
Access Control and Security
For starters, you can deny computers on the LAN access to the Internet, and you can specify clients by IP or MAC address.
The unit also supports both URL filtering (using only keywords) and domain filtering. If you attempt to ping a forbidden URL to get the address, it will be resolved, but entering it into the browser will result in nothing but a terse message telling you you're blocked. The ping request itself even times out.
The DI-604's firewall, actually lets you specify rules for incoming and/or outgoing traffic, based on all the appropriate variables like traffic type and port numbers.
Any of the aforementioned access control and security feature mentioned here can be scheduled by day or time of day (and very granularly, in five minute increments). You can even schedule things like virtual servers, to limit your exposure when you don't need to have certain ports open to the world.
The D-Link DI-604 packs a lot of features into its diminutive chassis.
Unless you need major integrated features that the DI-604 lacks, (like a print server, modem backup, or wireless LAN) you won't need to look much further than this D-Link router.
