How to diagnose and fix GlobalProtect when the VPN shows connected but no internet access.
GlobalProtect is a popular VPN client used by many enterprises to extend secure access to corporate networks. When it connects but you can’t reach the internet, it can feel frustrating and puzzling. In many cases, the problem isn’t the VPN itself but how the VPN tunnels traffic, how routes are set on your device, or how your local network interacts with the VPN. This guide walks you through practical steps to diagnose and fix the “GlobalProtect connected but no internet” scenario.
Quick checks on device status and network indicators

Understanding why “connected but no internet” happens
What “connected” means in a VPN context
When GlobalProtect shows connected, it means your client has established a secure channel with the gateway and can authenticate. However, internet access requires proper routing rules to let non-corporate traffic and corporate traffic flow correctly.
Common culprits
- Full tunnel vs split tunnel behavior: In a full tunnel configuration, all traffic is routed through the VPN, which can initially cut off access to local internet if the VPN gateway or route configuration isn’t handling non-VPN traffic correctly.
- Route conflicts: The VPN client may push a default route that takes precedence over your normal internet route, leaving you with no path to the wider internet.
- MTU issues: If the MTU is too large, packets may be dropped, causing perceived “no internet” or intermittent connectivity.
- DNS problems: If DNS requests are forced through the VPN or aren’t updated after the tunnel comes up, domain names won’t resolve, giving the impression of no internet.
- Firewall or policy blocks: Corporate or local firewall rules might block certain traffic while the VPN is active, leading to blocked internet access.
Quick checks you can perform on your device
Verify the VPN status and routes
- Check the GlobalProtect status: ensure it shows connected and healthy.
- Inspect routing table:
- On Windows: open Command Prompt and run: route print
- On macOS/Linux: open Terminal and run: netstat -nr or route -n get default
- Look for a default route (::0/0 on IPv6 or 0.0.0.0/0 on IPv4) that points to the VPN interface. If the default route is missing or points to the VPN, you may have a no-internet symptom.
Check DNS configuration
- Try nslookup or dig for a known domain (e.g., pinging www.google.com by name).
- If DNS fails while connected, try configuring a public DNS (e.g., 8.8.8.8, 1.1.1.1) and see if it restores name resolution.
Test basic connectivity
- Ping a known internal resource (if allowed) and an external site (e.g., 8.8.8.8) to distinguish local, VPN, and internet routing issues.
- Temporarily toggle split tunneling (if your IT policy permits) to see if internet access returns when only corporate traffic goes through the VPN.
Examine MTU
- If you’re on Windows, try lowering MTU slightly:
- Open a Command Prompt as admin and run: netsh interface ipv4 show subinterfaces
- Then set MTU to a smaller value on the VPN adapter: netsh interface ipv4 set subinterface "VPN" mtu=1400 store=persistent
- If you’re on macOS, you can test with ping -D or a similar MTU test to identify fragmentation issues.
Quick diagnostic workflow decisions
| Step | Condition | Action if Yes | Action if No | Tools to use |
|---|---|---|---|---|
| 1 | VPN connected | Proceed to test internet | Reconnect VPN | VPN client, ping |
| 2 | PING works | Test DNS/HTTPS | Check firewall | Command prompt, traceroute |
| 3 | DNS resolves | Access site by IP | Check DNS suffix | nslookup, dig |
| 4 | Site loads via VPN | Issue likely routing | Check split/full tunneling | Routing table, logs |
| 5 | Site blocked | Review policy | Escalate if needed | IT policy, admin panel |

Configuration options to consider
Split tunneling vs full tunneling
- Split tunneling: Only corporate traffic goes through the VPN, while other traffic goes through your normal internet connection. This often resolves “no internet” symptoms if the VPN gateway is not handling non-corporate traffic well.
- Full tunneling: All traffic routes through the VPN. If you experience internet loss here, it’s usually a routing or gateway issue on the VPN side, or a misconfigured client policy.
Firewall and security software
- Some antivirus or firewall suites block VPN traffic or alter routes when the VPN connects. Temporarily disable non-essential security software to test whether it’s the source of the issue.
- Check Windows Defender Firewall or macOS PF/NAT settings to ensure VPN traffic isn’t being blocked.
DNS over VPN vs local DNS
- If your organization uses internal DNS for the VPN, ensure it doesn’t prevent external name resolution. If the VPN enforces internal DNS only, consider enabling a fallback DNS when internet access is needed outside corporate resources, if policy allows.
A practical 4-step diagnostic workflow
- Confirm behavior and collect data
- Take screenshots of the GlobalProtect status and the routing table.
- Note whether DNS resolves names or only IPs ping works.
- Record when the problem started and whether any configuration changes were made.
- Test routing and MTU
- Verify default routes on your device when connected. If the VPN adds a VPN-specific default route but your primary internet path is interrupted, try adjusting split tunneling or removing the default route from the VPN if your policy allows.
- Run a basic MTU test: try pinging a known external IP with DF set and adjust MTU if fragmentation is observed.
- Check DNS and name resolution
- If DNS fails, manually set a public DNS server temporarily to see if browsing resumes.
- Verify whether internal corporate DNS is required for internet access, and whether it should be in fallback mode.
- Review logs and escalate if needed
- Gather GlobalProtect logs: on Windows, you can access logs via the GlobalProtect app or the Windows Event Viewer. On macOS, check the Console app or GlobalProtect logs in the system library.
- If you still have no internet after attempting fixes, contact your IT department with the logs, including:
- Time of connection
- IP addresses assigned
- Route table output
- DNS query results
- Any error messages observed
Practical troubleshooting steps by scenario
Scenario A: Full tunnel with no internet
- Confirm whether there is a corporate policy enforcing full tunneling.
- Check for a faulty default route through the VPN. If your policy allows, adjust to restore local internet routing while keeping VPN for corporate resources.
- Temporarily disable the VPN’s default route and test general connectivity.
Scenario B: Split tunneling but no internet on external sites Dreme & ecovacs comapre modules in amezon
- Ensure the split tunnel policy sends only corporate traffic via the VPN.
- Verify DNS behavior: some VPNs push internal DNS servers. You may need to add public DNS servers as a fallback.
- Test with a different browser or device to rule out application-level blocks.
Scenario C: DNS-only issue
- If you can ping IP addresses but not domain names, focus on DNS configuration.
- Try a manual DNS change, then revert to corporate DNS after testing.
- Check if DNS leaks or DNS suffix search list is misconfigured by the VPN client.
Scenario D: MTU-induced drops
- If you observe intermittent connectivity or pages loading but failing later, MTU misalignment can cause large packets to be dropped.
- Reduce MTU on the VPN adapter and test across multiple sites to confirm.
A useful comparison: split tunneling vs full tunneling
| Feature | Split tunneling | Full tunneling |
|---|---|---|
| Traffic routing | Only corporate traffic sent through VPN; internet traffic uses local connection | All traffic routed through VPN gateway |
| Internet accessibility | Usually retains local internet access; can resolve no-internet symptoms | Internet access depends on VPN gateway routing and policy; more prone to no-internet if gateway misconfigured |
| Security posture | Moderate; more exposure on local network but easier for troubleshooting | Higher isolation but more sensitive to gateway routing and policy correctness |
| Typical fixes | Adjust split tunneling policy, DNS fallback, MTU tweaks | Check gateway routes, MTU, DNS, and firewall policies on both client and VPN side |
When to involve IT or escalate
- If you’re in a managed environment and you’re seeing persistent no-internet despite following steps, contact your IT department. Provide:
- Your operating system and version
- GlobalProtect version
- Time of connection and observed behavior
- Outputs from route print/netstat, and DNS test results
- Screenshots of the VPN status and any error messages
- Some organizations require specific configurations, and changing tunnel settings or MTU could violate policy. Always align with IT guidance.
Configuration options comparison
| Option | Description | Pros | Cons | When to use | Notes |
|---|---|---|---|---|---|
| Split tunneling | VPN traffic splits between VPN and internet | Faster local access; reduces load | Security risk if sensitive apps bypass VPN | When internal resources not needed | Ensure policy allows it |
| Full tunneling | All traffic via VPN | Stronger security; centralized control | Higher latency; VPN load | When handling sensitive data | Requires adequate bandwidth |
| DNS through VPN | VPN provides DNS resolver | Consistent name resolution | May leak DNS if misconfigured | If internal domains used | Verify DNS leakage controls |
| Kill switch | Blocks traffic if VPN drops | Prevents leaks | May block all access | During uncertain connectivity | Keep updated |
| Auto reconnect | VPN auto-restarts on drop | Maintains session | May trigger loops | Unstable networks | Test stability |

Best practices to prevent future issues
- Keep GlobalProtect client and OS updated to the latest supported versions.
- Document any changes to VPN settings and notify IT before applying them on work devices.
- Use stable DNS servers and avoid mixing private/internal DNS with public DNS unless policy allows.
- If you rely on split tunneling, understand which destinations are proxied through the VPN and which are not, to prevent traffic leaks or access issues.
- Use a predictable network environment, avoiding multiple VPN clients or proxy tools that could introduce route conflicts.
Final recommendation
If your GlobalProtect VPN shows connected but no internet, start with a methodical check of routes, MTU, DNS, and split tunneling settings. Most cases resolve by adjusting the VPN’s default route behavior (split vs full tunneling), limiting MTU to a safe range, and ensuring DNS resolution functions when the VPN is up. Keep logs handy and collaborate with your IT team, especially in managed environments, as VPN configurations often depend on organizational policies. By focusing on routing and DNS first, you can often restore internet access quickly without resorting to drastic measures. ProtonVPN: Understanding its strengths, drawbacks
