Are using L2TP or Anyconnect?
I am using L2TP
This describe your issue as well?
So getting feedback from my users, anyone that did not do fresh VPN connection attempt in last 2 hours or so is still connected to VPN fine and can access the shared drive on our network. Any new connections get connected very briefly then dropped. Some get an error, some don't. Has to be an ongoing issue with Meraki MX firewalls since issue just started in last few hours.
It is really common for Windows security updates to reset the VPN settings on machines. Have any of these machines had a recent Windows update?
You can create a powershell script using my wizard to make it easier to re-deploy the VPN settings.
So an update, I sometimes add IOC IP addresses that are C2 to our Meraki Content Filtering / URL Filtering list.
I was testing VPN connection from home last night and got an error from http://wired.meraki.com:8090 blockng IP address - 13.107.4.52
I checked my URL list and saw that IP had been added by me earlier in the day, I removed it and bingo VPN connection stayed connected. Virus Total has mixed reviews on this IP, see below. Cisco Umbrella Investigate shows safe as well.
