I have 2 CVPN 3000 at my institution. They have both software version 4.7.2.L-k9. Thay also have WebVPN running.
Lately something strange has been happening. One VPN loses connection (ping keepalives stop working) and no one can connect. When this happens I change the dns A record of the vpn service to the 2nd CVPN and, after a while, that 2nd CVPN stops responding. Can this be an attack? What can I search for in the logfile? The logfile cannot handle more than 15, 20 minutes.
Thanks in advance.
