Enable Interface: OPT1 (OpenVPN) shuts off internet

[Spectrum48k]

Home pfsense box used as a simple router, 1xLAN 1xWAN

CA set up
OpenVPN Client set up
Interface for OpenVPN set up
No other settings have been added

The moment I enable the OpenVPN interface, OPT1, and reboot, I don't get any internet - I should be able to simply enable the interface without affecting anything, shouldn't I?

Checked SYSTEM > ROUTING and WAN_DHCP is set as the default gatway

The moment I disable the OpenVPN interface, OPT1 and reboot, internet is restored

Any ideas?

If the server pushes the default route to you and you did something wrong that's normal.

You may aviod to get the default route pushed by checking "Don't pull routes" in the client settings for testing.

Maybe you're missing the outbound NAT rule for the vpn.
So enable the interface and set the outbound NAT rule. The outbound NAT must be set to hybrid or manual mode.
Then add a new rule:
Interface: <the vpn="" client="" interface="">Source: any
Dest: any
Translation: Interface address</the>
