I'm looking for a cheaper equivalent to the Netopia R2000 analog dial-in router. Basically, I have a piece of equipment at a customers site that I need to access for remote troubleshooting. The Netopia allows me to dial-in to it, assigns me an IP address that's on the subnet of the machine, and allows me to run various programs as if I'm right there on the network. The Netopia runs $500. Any thoughts?
