Summary: Great value, outstanding phone support, decent learning curve you're new to enterprise grade networking and especially if you're new to networking in general.
Pros: Device is very powerful as far as configuration and capabilities go. I'm only subscribing to Intrusion/Anomaly Detection and Antivirus but they seem to work well. IDP has blocked a few intrusions attempts (we've been under attack and a Linksys SOHO router/SPI firewall didn't stop it; but this has).
Cons: This device seems to straddle SOHO and enterprise gear as far as features go. It's powerful but has a decent learning curve. Not really a con since adding capability also increases complexity; just be sure to leave time to play with the device and learn before dropping into production on a deadline. Again it's not really a con; it is what it is. And Zyxel phone support certain makes up for the added complexity.
Summary: Like every router, this has its own set of peculiarities. Things that are called one thing by vendor have a diffrerent name. Once you get past that, it is a very robust router. I compared it to Cisco products with the same functionality and this won hands down for my small 4 site network.
Pros: Great throughput, handles multiple VPN tunnels with no problems. Price is right and so far, reliability seems good. Top notch tech support.
Cons: Configuration can be a bit tricky. Some things which were supposed to work automatically (as per Zyxel support) didn't. One example is that when you have multiple subnets, they are supposed to be able to talk to each other by default. Not the case. Had to define policy routes and firewall rule to specifically allow.
Summary: I'll echo what the previous reviewer said. Let's understand exactly what this is: a reasonably low cost, business-class router/firewall. We needed one that had dual-WAN support, and it came down to this and a couple of Cisco's lower end offerings. Given the relatively poor reviews of the Cisco's, I decided to give the USG50 a whirl. After several months of continuous service, I'm glad I did.
Pros: Reliable, Highly configurable, Dual WAN support, good Tech Support, good value.
Summary: This firewall has by far improved my networks performance as well as the ability to customize connections and routing policies.
Pros: EXTREME CUSTOMIZATION!! I have configured certain protocols or websites to route through one WAN connection or the other, block XBOX Live or Playstation Network during specific times, etc. etc. etc. If you have a need for protocol or IP routing requirements this is the device to have. For the price, the features cannot be beaten. Logging and capture features are epic, I've identified bots hitting my networks every 2-3 hours along with malicious attacks with ease. I've...
Cons: Learning curve to set up, it's definitely not your average Netgear or Linksys box. My advice, set up all your IP addresses, services, and groups under "Objects" before you even go into setting up NAT/Firewall or policy routing. Once you configure all the "Objects" you need setting up new rules, policies, etc. is very easy and straight forward.
Summary: I've never purchased a ZyXEL product, and I've only owned this one a few weeks. Ergo, I can't comment intelligently on how durable they are over the long run. Also, I'm a programmer with a fair amount of depth, and I've configured my share of networks, but those have mostly been small business and home setups.
Summary: As a first-time ZyWALL user it took me under a half-hour to upgrade the firmware and get it passing traffic lan-wan. It did take a few hours to get it 'fine-tuned'(nat/firewall rules, general poking around and reading up on features, etc)
Pros: -Easily handles 100/6mbps cable connection
Cons: Well its not much of a con but it would be awesome if these had a built-in power supply instead of a wall-wart - a bigger chassis would be fine by me.
Summary: Had this puppy (actually 2 of them) for over a year now running a small biz with all kinds of bells and whistles. Solid performance for VOIP, data and VPN. This little gem is the center of my IT universe and it has not let me down for over a year even when one of my employees decided to plug in a POTS line into one of the ports! Because of redundancy (and affordable price), I bought 2, but did not have a need to fire up the other than for testing scenarios.
Pros: amazing little product packed with features that can support a small biz in an enterprise way. dual wans, IPSec, SSL, object based configuration, easy setup and actually decent documentation! Just one heck of a beefy little router for the price. Oh and did I mention the very friendly and knowledgeable FREE tech support I got from ZyXEL when I was troubleshooting some of my hosted PBX issues? They were right on with their analysis and instructions -- took me 5 min to s...
Cons: not a con of the router but the IPSec software that is sold by ZyXel to accompany this product needs help, lots of help.
Summary: This is a great product. I have used this for a good 2 months solid with no problems what so ever. Took a few hours to get it setup and working. Dual Wan is very cool, if you have never used on before like I had. This thing has more settings you can change which is good and bad. Good for people who know what they are doing, bad for ones who don't know it all.. I can setup just about any "home" router, but this thing took a bit longer.
Pros: Works, Great Security Features, More settings then i know what to do with
Summary: After having setup many, many routers from all brands, these were a pleasant surprise. A lot of consumer and SOHO routers are quirky beasts, shipped with long-term instability issues or features that plain out don't function. Even ones from the very well known brands available at your local "big box" electronic store! You'd think those would just WORK, but often they don't—at least, not all the time.
Pros: Based on the three USG 50's and one USG 20W that I installed over the last two months, I've found that they are:
Cons: * While setting up a basic home network (1 WAN, 1 LAN, VPN passthru, DHCP) is pretty easy, using the remaining 90% of the features requires some networking expertise.
