hi ,
click on Diagnostics -> Logs -> PPTP VPN and you can see who is logged in.
Many Thanks
Thanks for you help!
But since I can't tell from those logs if the users are still online or not, I ended up using angry ip scanner to scan the ip pool I used for PPTP to see what IP's respond. Then I can cross reference this to the logs you mentioned. So I am ok now.
I just want to keep an eye on the usage of the box. Once again, thanks
