hey IT nerds! opinions on vpn concentrators for user->office vpns?

[rmd]

I've got an office full of people who like to work from home by VPNing in to the network, here. So, the cisco 3000 vpn concentrator is a nice enough box. Well, except for the fact that it's busted and old enough that the product line is end-of-life.

What are folks using? What's good out there, these days? I'd like a whole lot more flexibility in terms of configuration, and also the ability to do things like https tunnels instead of being limited to vpn client software on the user's machine.

thanks!
