My company has a user leaving the office and will be working from home often. I need to setup a VPN connection for him. Here is the situation.
- The user will be working from remote locations. The remote IP address won't be static.
Our network setup is as follows:
a. Internet comes in from a cable modem and has a static IP address, which is known.
b. The modem is connected to a Linksys/Cisco RVS4000 VPN Firewall/Router. This device has a static IP address on our internal network and does not provide DHCP services to the network. Its firmware version is 1.3.2
c. The RVS4000 is then connected to our internal network. Everything on the internal network is in the same subnet and their IP addresses are assigned by a Windows Server 2003 domain controller.
The user needs to be able to access network resources first and foremost. Ideally, he should be able to authenticate with the domain as well, but that is secondary. Authentication with the domain will make it easier to access the intranet.
What I have looked at and tried:
Linksys/Cisco quickvpn client. This thing has never worked across all firmware upgrades. Maybe I am doing something wrong. Using this, I have set up user accounts on the RVS4000, exported a certificate and put it int he quickvpn directory on the remote machine. It does not work when I try to connect. It won't establish the connection.
ShrewVPN client: I am not entirely certain how to configure this.
OpenVPN: Due to limited linux-fu, I haven't gotten very far.
At this point, I am ready to be treated like an idiot. Apparently I am missing something and don't know where to start.
