Summary: I bought this product in 2009 and it has work OK for the must. I have noticed that the internet speed slows down when connected via the router versus connecting directly via the cable modem. The VPN functionality is not so good and do not contact Linksys customer support ...
Summary: Not too much more expensive than a regular router, this device works in conjunction with another VPN endpoint (for instance another of the same model) to establish a secure VPN, making it a snap to create secure tunnels between two remote locations.
Summary: I purchased the BEFSX41 to replace another I had at a client remote office, creating a VPN back to the home office with a BEFVP41. In my 8+ years of using the BEFSX41, carefully deployed with surge protection and in climate-controlled environments, I have found that they are not reliable.
Summary: We use these routers to connect two offices using the VPN feature. We have used Linksys products since 2004 and were very happy until recently. In the last 2 years we have gone through 4 of these routers.
Cons: Bought 2 of these for 2 different locations in January. Configured one offsite, and upon installation would prompt for username and password, would not load the config and wasn't allowing network traffic. The second one worked for 3 months and did the same thing. Never again.
