Im having issue with my VPN configuration.
Here are the detail:
Devices:
Laptop using the Palo Alto Networks(GlobalProtect) VPN for work
OPNSense firewall with OpenVPN server
Slate AX(GL-AXT 1800) with OpenVPN Client which connects to OPNSense firewall
Connections:
Slate AX connect to OPNSense with OpenVPN, all traffic from router goes to firewall
Laptop connect to Slate AX by wifi
GlobalProtect on laptop will connect to my company via Internet
Expection:
I expect my laptop traffic will through the slate ax to OPNSense then connect to my company.
It will guarantee my traffic will exit from my firewall.
It will also guarantee my laptop public IP address will stay with OPNSense’s public ip.
Issue:
Now, OpenVPN works fine untill the laptop connets to Slate AX and enabled the globalprotect VPN on laptop.
The error shows the Internet can’t be accessed with IPv4 protocol
I don’t think so. My other devices(without GlobalProtect VPN enabled) successfully connect to Internet via Slate AX & OpenVPN.
The screenshot I attached above only happened with my laptop that has the GlobalProtect VPN enabled.
In other words, The OpenVPN tunnel works fine for my other devices but this OpenVPN tunnel got break when global protect VPN enabled.
