I work at a small company that has two offices, each with its own Business DSL connection to the Internet. In order to create a LAN between the two offices, my predecessor purchased and installed two Linksys WRV54G Wireless VPN Broadband Routers to provide a hardware solution to make the computers at both locations see each other and think they are on the same LAN.
Despite keeping up with every firmware update, I still finding myself driving to one office or the other (it's almost always the office I am not at) about once or twice a week to power-cycle its router to either get the wireless part working again for somebody's laptop, or to get the Internet gateway part working again. The VPN tunnel always seems to stay up, however.
I am looking to replace these WRV54Gs with something (perhaps multiple pieces of hardware) that can perform all the functions of the WRV54Gs, but that don't misbehave so much. It will be easy to just pick up a wireless access point off the shelf. It will be similarly easy to pick up a couple 8-port switches off the shelf. The real trouble is that I can't seem to find any hardware to do the VPN part. I want this to be completely hands-off the workstations, so it has to be a hardware solution.
What type of router can I use to work as an Internet gateway for our Business DSL connections, as well as be the endpoint of a VPN tunnel that, for lack of better terms, fools windows into thinking that the remote LAN is actually local?
