I have a Checkpoint firewall that is of course used for security, but also VPN access. In the past users would VPN to the public IP of this firewall, using their domain credentials to authenticate. For whatever reason users are now unable to VPN with their domain credentials. If I attempt to VPN it fails - within the Checkpoint Event Log I can see this failed attempt (ip address is censored):
"Connection from ip 7x.9x.1xx.7x with user sknoll failed. Reason of failure :User authentication by VPN-1 failed."
We have disabled VPN, rebooted. Re-enabled VPN, rebooted and still no success.
Yes, if we create local users within the Firewall I can log in this way, however we would like to authenticate our domain credentials.
