Hello Guys! I've got a serious problem! I'm using TomatoVPN 1.27 VPN 3.6 on my Linksys WRT-54GL router. (Interface type: TAP, with DHCP) I've generated many OpenVPN certificates. Most of them are valid for one year. One of my employees has disappeared with a business notebook. I have to block his every attemp to connect. How to do this? If you have any ideas, share please. I will be very grateful! Thank you in advance. Tom
