I have a VPN that I connect to to be able to access the remote desktop of some virtual machines I have behind a Sophos firewall.
Up until last week everything was fine.
Now when I am connected to the VPN I can sill access the remote desktop but all other internet access is lost. My wifi connection says “no internet”.
A colleague of mine has no issues.
I have tried deleting and recreating the VPN connection.
It sounds like you might be experiencing an issue where your VPN connection is routing all your traffic through the VPN tunnel, including your internet traffic, which isn’t able to reach the internet through the VPN’s network. This is often referred to as a “split tunneling” issue in VPN configurations. Here are some steps you can take to troubleshoot and potentially resolve the issue:
Check VPN Configuration: Verify if the VPN configuration on your machine matches that of your colleague’s who isn’t experiencing the issue. Particularly, look for any settings related to routing or split tunneling. In some VPN setups, there’s an option to route only local network traffic through the VPN, while allowing normal internet traffic to use the regular route.
DNS Settings: Sometimes DNS settings get changed or are not properly configured to work with VPN networks. Check your DNS settings and compare them with those of a working setup (like your colleague’s). You might need to manually set your DNS to a public one like Google DNS (8.8.8.8 and 8.8.4.4) or use the DNS suggested by your network administrator.
Firewall and Security Settings: Since your machines are behind a Sophos firewall, ensure that no new rules or policies have been applied that might be affecting your connection. Perhaps, a rule that affects only your user profile or IP could have been inadvertently set up.
Network Adapter Settings: Sometimes, VPN installations can alter the network adapter settings. Check the properties of your network adapters to ensure they are configured correctly. Look for settings related to IPv4 and IPv6.
Reinstall VPN Client: You mentioned recreating the VPN connection, but it might also help to completely uninstall and then reinstall the VPN client software. This can resolve any corrupted files or settings from the original installation.
Update Network Drivers: Ensure that your network drivers are up to date. Outdated or corrupted drivers can cause issues with network connectivity when using VPNs.
Check with IT: If the above steps don’t resolve the issue, it might be a good idea to check in with your IT department if you have one. There could be changes or updates in the network configuration that they are aware of, or they might need to reissue your VPN credentials.
By systematically checking these areas, you can identify whether the problem lies with the local configuration, the VPN setup, or perhaps something specific to the network environment.
The issue was in the router. When I connected to my phone’s hotspot it worked fine.
I turned IPv6 on on my router and it seemed to fix the issue.
