I have two users who recently started experiencing issues with their VPN disconnecting their network connection. It doesn’t matter if the laptop is connected via Wi-Fi or Ethernet. We use the built-in Windows VPN. I removed the old connection and reinstalled it, but the results are still the same. I suspect it’s a recent Windows update causing the issue, as restoring the device to an earlier point temporarily resolved the issue for a few days. Once you disconnect the VPN, the network connection is quickly restored. Thoughts?
Sounds like a windows update may have enabled Use Default gateway on remote network.
On network adapter for the VPN Properties>Networking>TCP IPv4>Properties>Advanced and make sure that Use Default gateway on remote network is not checked off.
If that is check marked and they are on the VPN they’ll lose access to their local network and can do weird things with accessing the internet as well.
I owe you a beer. That’s exactly what it was. Thank you!
Well, that fixed part of the problem. We gained network connection but can’t connect to shared drives. When that setting is enabled we gain shared drives but lose internet again. I can also remote in to the users device even though the network connection shows no internet.
Are these local shared drives or the shared drives on the VPN?
If you are using named shares like net use s: \storage\files when he connects to the vpn it will likely fail in resolving the ‘storage’ server because it’s now using the VPN for dns.
If you change your mappings to IP’s net use s: \\192.168.1.20\files they should be able to access them while on the vpn.
They are named shares. We finally figured out it was a setting on our firewall “Apply firewall policies to intra-interface traffic on the current interface" and that allowed everything to work.
