Summary: This is the second Linksys BEFVP41 router that I've purchased. The first one was new and cost $120. It had a serious internal short that would reset itself with just a bump of the desk. The next one I bought used on Ebay and it doesn't work at all, because of internal problems. I then purchased a Linksys BEFSR41 used on Ebay, and now everything works great! It was about the same price as the other model, approx. $20.
Summary: I read the manual before doing anything else. (Always a good idea!) Unfortunately the manual was written pre-vista. (I bought mine used.) I went through all the steps, called my ISP and got the relative numbers. Then I hooked it up and turned it on. Lo and behold, vista did all the setup automatically! All I had to do was show it what folders I wanted to share between computers.
Summary: This is a great router with lots of features. If you are running a home network for personal use, you probably will never need this. But if you are a small business and you are concerned about internet security, you should take a good look VPN routers and this Linksys system.
Summary: The BEFVP41 is a great and relatively easy to setup router for someone with some basic understanding of VPN networks. The manual is ok but you've got to know a bit about networks otherwise it can be a bit confusing. It is not an impossible task though. The version 2 of the router is the preffered one since it has more refined software. It has settings for QOS that are very important if you have a VOIP router also attached to the BEFVP41.
