VPN IP was working for 3 weeks then suddenly got blocked

Hey Michael Aliviado 

Welcome to the Sophos Community!

Would it be possible to enable the Support Access tunnel on your firewall and PM me the ID for further investigation?

Thanks!

Hi Flo,

Thanks for your reply. I will try what you advised and will send you a DM for the support access. What I have diagnosed so far was that the VPN login they used changed 2 days prior to the disconnection but still use the same IP. Just give me a day or two to respond back with the support access as I am working on a more critical problem.

Hi Michael ,

There must be some changes here.

Possible Changes, the port used is 443 do you use a VPN portal or connection using 443.

Ipaddress category was added to the web filter or changes been made to the policy assigned to the firewall. 

Hi Aditya,

Thanks for your Response. No Changes were made to the Firewall. The only change I knew was that the login for their VPN change but still used the same IP address the same IP address which has been working before the incident happened. 

I am trying to trace back the record by using Reports > Custom Reports >Custom web reports. It only gives me the data below. No Port destination. Is there a way to generate a more detailed report? Log Viewer only shows data for a few days and not in the long run. I can no longer get the same data as what I first posted above.
