AD Authentication Time-out

This issue just started on Sunday, reoccurred just now.

Remote VPN login times-out. I've narrowed it down to an issue with the FW connecting to AD. The "Test Connection" failed. A reboot of the FW fixes the issue (Both times).

After reboot, the "Test Connection" succeeds with no changes made other than the reboot of the FW.

Can you direct me where to start with this issue? I can't find anything relevant in the FW logs.

This is an XG125 with 20.0.2 MR-2-Build378

Authentication is in /log/access_server.log. I have no idea if it will contain anything about VPN logins. Hopefully it does. I do know, however, that it contains logs every time you Test Connection. Perhaps…

Thanks for that....

I see that the FW is getting hammered with brute force attacks, on the VPN Portal, which I have turned off, but its still accessible....

ok, I figured this out.

Now the VPN Portal is given the default port of 443. If you have your Remote SSL-VPN also set to port 443, then you cannot turn off the VPN Portal.

To turn off the VPN Portal now, you have to go change the default port of the VPN Portal, which I just did (to 8443).

Now I can turn off the VPN Portal.
