Why can't I access local network devices while connected to OpenVPN?

The issue is likely due to OpenVPN settings blocking local network traffic or router settings preventing local access while the VPN is active.

Allow Local LAN Access in OpenVPN:
1. Edit the OpenVPN client configuration file (.ovpn).
2. Add or update the following line to allow access to the local network:
ini
route 192.168.1.0 255.255.255.0

(Replace 192.168.1.0 with the actual local network subnet.)
3. If there's a redirect-gateway rule, modify it to allow local traffic:
ini
redirect-gateway def1 bypass-dhcp bypass-dns


Enable Split Tunneling:
1. If using OpenVPN GUI:
- Right-click the OpenVPN tray icon β†’ Settings β†’ Advanced.
- Enable 'Allow LAN Traffic While Connected'.
- Restart OpenVPN.
2. If using a company-managed VPN, the administrator may need to allow split tunneling for local traffic.

Check Router Settings:
1. Log in to the router’s web interface.
2. Disable settings such as AP Isolation or Client Isolation.
3. Ensure LAN-to-LAN traffic is allowed.

Check Device Network Configuration:
1. If a local device (e.g., printer, NAS) has a static IP, ensure its default gateway matches the router’s subnet.
2. Example: If the router’s IP is 192.168.0.1, ensure the device IP is within 192.168.0.x.

Add a Static Route (Advanced):
1. If the VPN changes the default route, manually add a static route.
2. Open Command Prompt as Administrator and run:
sh
route add 192.168.1.100 mask 255.255.255.255 192.168.1.1 -p

(Replace 192.168.1.100 with the local device IP and 192.168.1.1 with the router IP.)

Final Steps:
- Try accessing the device again.
- If still not working, test connectivity while on VPN by pinging the device IP.
sh
ping 192.168.1.100

- If the ping fails, the VPN is likely blocking local network traffic.
