I need to create a VPN, so that remote users can dial in to our company network, to access resources on the network. I do not need a branch-to-branch VPN.
I have the following:
- Netgear DG834 ADSL modem/router
- ADSL line to be used only for the VPN. No static public IP address on this line, but a DynDNS hostname can be set up easily.
- Windows Server 2003 Standard license
- Intel server with 2 network cards (I assume one will point to the internal network, and one to the router's "network")
- Existing network with +- 40 PCs, devices, servers, etc that we need access to
- No Windows Domain or Active directory
I've been playing around with Routing and Remote Access (RRAS) on the server and the VPN Wizard on the DG834 router, but haven't been successful.
I really don't think I can progress until I have answers to the following:
- Can I set up the VPN only on the DG834, without needing the server?
- Can I set up the VPN only on the server, without need the VPN features of the router?
- If I use RRAS, do I need to open ports on the Windows server firewall, or will RRAS handle this automatically? When RRAS is enabled, I can't access the Windows Firewall to set up any inbound or outbound rules.
- How do I know which VPN protocol to use, that is supported by both the router and the server.
- What VPN client do I use to dial the VPN connection? Can I use the built in VPN client provided by windows ("Connect to workplace")? I would prefer to set the VPN up without needing to pay for any softare or licenses.
Are there any guides out there that can assist with creating a VPN for the environment I've described above? I've done quite a bit of reading already, but nothing that is comprehensive enough to help me out.
