Hello, I'm a PC tech that's way in over my head. I have a client that I've promised a VPN to; and some functionality and features that I'm not really sure how to set up and implement. As a consultant/tech for mainly SOHO offices, I'm pretty familiar with networking, however this one goes way over my head. The situation: the client's got 2 offices, 50 miles apart, that uses a server/client application where the data is stored in plaintext in a folder on the c:\ drive on the server. The application does work over a network, I've had success mapping the data folder from the server to peer clients on the LAN. Basically, in a single office environment, the program works perfectly, as it should. From my rudimentary knowledge of VPN's, I should be able to set up a tunnel between the 2 offices where they can access the data via mapped folders, and thus be able to use the application. In addition, they should be able to get on the 'net without any problems without taking down the tunnel. The tunnel must be up at all times, and their PC's, shared folders and connected printers should be available from either end. After figuring out what they wanted, I went ahead and purchased 2 Linksys WRV54G's, even though the RV042's plus a WiFi AP would be a better. The setup: In office #1 (home) - Comcast HSI cable, averaging 3mbps/400kbps. The server is running XP Pro, SP2. There is an HP AIO, plugged directly into the server, but it's got a print server built in, so that may be used in the future. The data, of course, is stored here on the server. Their WAN IP changes once every 100 hours, so I've set up a dyndns account which should track the WRV54G. In office #2, they've got a 2 XP Pro SP2 systems, and the same Comcast setup. An HP printer has been plugged directly into one of the PC's, and is shared on the LAN. Of course, a separate dyndns account has been used for this router. On both ends, the LAN has been configured statically, beginning with 192.168.1.2 (.1 is the router) There are also 2 XP Pro SP2 laptops, and we've purchased USBVPN1's for both, just in case they travel, or go to a remote location with broadband acces. Because they're portable, they could be used in either locations, and access the data from the server over the VPN. Obviously, when they're on the same LAN as the server, there will be no issues. The firmware on both 54g's has been upgraded to 2.37. I'd like it set up so that the user can sit at the office from any PC behind the router, go into my network places, see the shared folders from home, and map them as a drive into my computer. Once the drives are mapped, I can pretty much handle it from there. They should also be able to simultaneously surf the 'net, and print to the shared printers, both on the local and remote LAN's. They should have the same functionality from home. The Question - first, money is no object, within reason. We went with the '54G because space is limited, but I did mention that the RV042's and a separate access point would be a better choice. As of right now, I've got both set up for 'net access, but can't ping either end - (xxx.dyndns.org) Am I missing something? I've even tried taking one of the 54g's home, where I've got 6mbps SDSL with 5 static IP's, no dice, (yes, the ddns is off at home) and can't even get into the configuration, even with remote administration on at port 8080. I'm sure that in order to see the PC's and folders, there should be some port forwarding, but they should be able to connect a tunnel first. It says the tunnel is connected, and from what I understand, everything is configured correctly. I'd rather not use a software solution as the VPN should be transparent, and must be up all day long. However, at this point, I'm willing to try just about everything - software, RV042's... Sorry for the long post, I'm just looking for a little guidance and suggestions from someone who's done something like this before. Any help would be appreciated, and don't hesitate to tell me if my VPN solution is way out of line and impossible. BTW, what's the difference between a VPN gateway, and a VPN tunnel? Thanks!
