I have changed my settings under as such:
Right now I have my Mac plugged in, and with these preferences the Mac should not go on sleep mode making the vpn off. Whenever I close my lid and reopen very quickly my Cisco connection basically is off immediately. The Mac is not going to sleep but nonetheless I lose connection. Is this a Cisco settings configuration that I should tweak and I'm not aware of, or is there anything else I can do on the Mac side to prevent this from happening ?
