Why might a pfsense gateway VM need a new static IP after a resume?

When you resume a vmware VM that is set up as a gateway using freebsd-based pfsense, networking on the WAN side no longer works after the resume.

Using pfsense's web configurator from the LAN side from another (client) VM, you can manually change the static IP of the WAN-side network interface IP from 192.168.2.33 to 192.168.2.44 and then it works.

Why might this be?

The guest operating system (freeBSD) seems to reset the settings of the WAN-side interface (which is a USB-to-ethernet adapter), after coming out of sleep, but keep the settings of the LAN-side interface which is a plain virtual network interface. Why would it do that?

EDIT: Just found it only happens with this USB-to-ethernet adapter, not with a regular virtual network adapter on the WAN-side.
