What do you do if your internet connection drops when connecting to the corporate VPN?

If your internet connection drops when connecting to a corporate VPN, you can take the following steps:

1. Check VPN settings: It is possible that a full tunnel mode is enabled, where all traffic goes through the VPN, and if the VPN server is not configured to route external internet traffic, access will be lost.

2. Split tunneling: Find out if the VPN supports split tunneling — where traffic to corporate resources goes through the VPN, and the rest directly to the internet.

3. Check DNS: Sometimes, after connecting to the VPN, DNS settings change, which can cause domain resolution issues.

4. Check routes: Use the route or ip route command to check which routes are set after connecting to the VPN.

5. Contact IT support: The problem might be on the VPN server side or related to security policies.

6. Restart network services or the computer: Sometimes, resetting network settings helps.

Thus, the issue is often related to routing and VPN settings, and its solution depends on the specific corporate network configuration.
