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

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!

the mystery deepens

so, i thought i had a roof leak, but the roof guys say that while there's some stuff that needs to be done, it's not enough to explain the level of water we're seeing in the basement.

so, now it's a mystery.

the only wet thing above the area of greatest wet is a radiator that doesn't seem to be the source of the leak.

the second floor bathroom gets its plumbing through the chase with that chimney, but i'd expect the main bulk of the water to come down the chase with the pipes if that were the cause. the 2nd floor kitchen is up against that side of the chimney, but there's nothing wet, there.

i'll have to get into the tenant unit and take a look at what's going on there. and then, i guess i start tearing off walls and figure out what the HELL is going on.

bonus question: how much subfloor in the first floor kitchen is rotted out?

ETA: Anyone local have a moisture sensor frob i can borrow to try and hunt where the wet is?
