Here at work we've got a Cisco SA540 I got set up for us last week. We've got site-to-site tunnels established, but for some reason I'm finding it incredibly difficult to get per-user VPN tunnels to work. I think most of the problem is that I haven't fully wrapped my head around how to set up user-based authentication for the tunnels in the first place.
The Cisco has a pretty sweet little web portal where you can go from an external PC to it, it'll silently install a VPN client in the background and after that you're good to go. This will save me a ton of time from having to custom-make VPN connections for employee's personal and work laptops. But when I try to log into the SSL site from anywhere outside of my internal network, the computers come up with "portal not found!" and won't let you log in.
The manual way of doing it doesn't seem to work either, I've got IPSec users established but no matter what, VPN connections just time out and never connect. Quite honestly I'd enjoy some formal training in situations like this, but now I'm in the last step of setting up everyone for VPN use so if anyone can walk me through why I'm getting the "portal not found!" problem or just a step-by-step walkthrough on how to create users to log into a VPN that would be wonderful. Thanks very much.
