Hotbrick LB-2 Load Balancing router -
Product: HotBrick LB-2 Dual WAN Router
Author: Anthony Sims
HotBrick is a relativly small company in comparison to the likes of Netgear and Linksys (Cisco). Despite their size, our IT guys have all heard of HotBrick (shame they dont use them though). However they have a nice array of network hardware, from $99 soho routers to $999 gigabit switches.
In this review we will be looking at a mid range product aimed more at the "so" part of "soho", as the product under inspection is the LB-2. A load balancing dual wan router.
We will look at the following points throughout the review:
- Setup and interface
- Ease of use
- Feature set
If you are new to networking, then you may want to read the next couple of pages, otherwise head straight over to the beginning of the review.
For those of you that understand roughly what a router does and have some grasp of the countless abbreviations that seem to clutter this subject, just skip over to the next section.
Lets start simply. You are reading this webpage through a link called guru3d.com, this link relates to an ip address (if you don't believe me, open a dos / command prompt and type ping guru3d.com). The ip address relates back to a physical machine in the world, which hosts this text. Your computer has a very similar setup.
The way your PC connects to guru, is through (amongst other things) routers. You are connected to your ISP through cable/dsl/dialup, now I pretty much guarantee that you are then passed through some form of router, which combines you and everyone else connected to the ISP, into another ip address. This (very simplified model) happens in both directions between you and guru3d. This process is called network address translation or NAT, and can be found in every off the shelf router. One last point about NAT is that there are two sides to it. The local side, and the world side. You are on the local side of your ISP and guru is on the world side of your ISP. When you get a router, you will be on the local side of the router, guru (and your ISP) will be on the world side of your router. The local side is referred to as the LAN side (local area network) while the world side is referred to as the WAN side (Wide area network).
e.g. PC A (192.168.0.1) <----> (192.168.0.254 - LAN Side) Router (22.214.171.124 - WAN Side) <----> Internet
NAT can be built on to provide various options that can be adjusted inside a router, and depending on how complex the designers of the hardware are, many administration functions are born e.g. Blocking access to the internet for certain machines on your network.
NAT is often referred to as a hardware firewall, this is my pet hate is NAT is NOT a firewall. Pure NAT does protect your machine from attacks, but only because the attacker does not have the required information to locate your machine. i.e. The attacker may have your routers address of 126.96.36.199, but hasn't got the routing information to get to your 192.etc address. A firewall can often be included in your router, however referring to NAT as a firewall is wrong (Rant over!).
Hotbrick brings us a dual wan router to enter into the market. Will it good enough... only a review can tell.
