I need to set up a VPN tunnel to a remote site and could use some good step-by-step instructions. The equipment at the remote site is a Netgear 7550 DSL modem/router. I need to connect to the entire LAN at the remote site , not just a specific computer. I have a Netgear FVS318N firewall to set up behind the DSL modem, and from there to the LAN switch/devices, so traffic has to go through the DSL modem and then through the firewall to the devices and back out.
A laptop will be used from various locations to tunnel in to this remote network and access devices on it.
I'm not wedded to the Netgear firewall, so other suggestions are welcome on that. I don't have much control over the DSL modem other than that I should be able to get into the interface for it when I'm on site if changes are needed.
