Life After AirPort -- New Wireless Base Stations
Pages: 1, 2

WEP has proven to be a relatively insecure protocol with many exploits; it also imposes a speed penalty to your wireless connection. Since I always use protocol-level security (such as SSH and SSL) for all of my network traffic that needs to be encrypted, relying upon this functionality to control client access is questionable. I would much rather ask a guest for his MAC address than give him a security key that he might assume provided adequate security for their usage.

Another problem that I found with this gateway was in its DHCP implementation. The DHCP server faithfully managed the internal IP address space of my network, but I found that it wasn't configurable enough for my needs. DHCP servers typically have the ability to give out specific IP addresses based on the Ethernet MAC address of a client. This allows my laptops to always get the same IP addresses when I am in the house, making it easier to ssh into my Mac OS X machine or to test services running on my Linux laptop. This DHCP server didn't allow me to assign specific IP addresses.

The HomeConnect gateway advertises that it logs attempts by hackers to penetrate the firewall. I was interested in this feature as I am always curious to see who may be attempting to jiggle the locks on my network. Unfortunately, when I tested this feature, I found that the logs were almost useless. The interface only presents activity that occurred during the previous few minutes, and has no capability for saving the information. Evidently it was designed under the assumption that you only need to know about hacker attempts while you are using the management tool.

The last problem that I had with the gateway was that I could only rest it flat on a horizontal surface. There were no mounting holes on the bottom of it to allow for mounting it on the wall underneath my desk. And, even if resting it flat on a horizontal surface was acceptable, the unit is designed with a hump on the top of it. This makes it impossible to stack anything else on top of the gateway.

Since I wasn't satisfied with the 3Com gateway, I decided to give the SMC Barricade a spin.

SMC Barricade

Like the 3Com product, the SMC Barricade was easy to connect up to my computers and to start up. However, the process to get the Barricade up and running with my ISP was a little less intuitive than the 3Com setup.

Instead of an initial setup process, the Barricade starts up with a default configuration that needs to be customized if your Internet connection doesn't fit its assumptions. In my case, I had to change the router so that it would not get an IP address from my ISP automatically, but would let me specify my WAN IP address settings. This is not a problem if you are pretty good with networking, but the 3Com product has an edge here.

Like the 3Com gateway, you manage the Barricade through a Web-based interface. Simply point your browser at for the unit's system status. The presentation of the page is not as polished as the 3Com unit, but it is functional and informative.

The Barricade's management tool isn't as pretty as 3Com's, but it is informative. (click to enlarge image)


As shipped from the factory, my test unit did not allow me to configure DHCP or wireless client control to the degree that I wanted to using MAC addresses. But a quick check of the SMC Website showed that a firmware update was available and added exactly the features that I wanted. After a very painless firmware update process, I was able to access screens giving me the ability to assign specific IP addresses to MAC addresses and to allow or disallow them from joining my wireless network. The only minor problem is that the HTML for the MAC Access Control pages would not work in OmniWeb (my preferred browser for Mac OS X).

In addition to the features that I required for my network setup, the SMC Barricade ships with a few other features that are interesting. The first is that it has an integrated print server. The print server serves both as a Unix lpr server (offline printing to server) and as a Windows print server.

In addition, you can have the router dial out on an external modem if the primary WAN link goes down for any reason. I have not yet configured this, but will be investigating this soon.

Just like the 3Com, it has a bulge at the top of the case which impedes the ability to stack items on top of the router, but there are screw-mounting points on the back of the case that allow the unit to be attached to a wall. It mounted like a charm to the wall underneath my desk.


The 3Com product is better suited for people who want easy configuration and don't have any specific requirements. My requirements are admittedly nit-picky. If you don't need this level of control, go for the ease of setup of the 3Com.

The SMC product is better suited to more advanced users who know how networks go together and are not put off by an interface that is not as polished. But when you need this level of control, go with the SMC. For my network, I kept the SMC Barricade. Needless to say, I am back in the happy zone where I can compute where I want, free of Ethernet cables.
