VPN setup and planning - peer to peer network - soho
Posted on 2010-08-26
I'm planning on setting up a VPN for a small office home office setup. All PC systems will be running WinXP and the requirement is to have a remote user connect to the office's peer to peer network. The remote user will only need to access one computer on the LAN. I have several simple questions that need to be clarified:
1. Is it mandatory that I purchase a VPN router or a UTM appliance with VPN capabilities?
I notice a lot of people on EE always talk about getting a VPN router to connect to another network. My current networks only use simple Linksys routers with no VPN capabilities. I do want to purchase a UTM appliance for this network in the future so I can enhance security.
2. Will I also have to purchase VPN client software in addition to this or can I use the built-in software of WinXP?
I can easily setup the VPN server and client configurations for WinXP but I'm not sure if they're secure enough to use. Can IPSEC and L2TP be setup easily on the WinXP built-in software?
3. I have about 7 computers on the LAN but I only need the remote user to connect to one of the computers. Do I need to order 7 static IP addresses or can I have one static address and the rest use DHCP?
I told my internet service provider that I needed only one IP address but I wasn't sure. I asked for assistance but they gave me the run around. They just said we have to upgrade your modem.
4. If you pick the latter method of setting up the VPN (one static and rest DHCP), how would you setup the network layout?
modem - VPN router - LAN(server inside)?
modem - server - router - LAN?
modem - router - server - switch - LAN?
