change system monitor quality from WAN_DHCP to something else?

[tswalker]

Is there a way to change this quality monitoring from WAN_DHCP to something else?

I have a use case where i'm testing cellular ISP services, and the tower has a specific IPV6 address that i would like to test against.

As it is, this device i'm using is hitting 660μ  which is.. fantastic, but not real lol  I need to hit beyond and would like to target different tower IPV6 addresses.

I just don't know how to do this OPNsense.

System: Gateways: Single

Then choose the gateway you want to change and enter the desired monitor IP into the field.
