ROBOGUIDE
The FANUC ROS 2 Driver can control virtual robots in ROBOGUIDE.
Robot Network Configuration
You do not have to configure the network settings of the virtual robot because ROBOGUIDE automatically assigns the port to the localhost of the host computer by default.
If the checkbox “Run virtual robots with loopback address” is checked, uncheck it to make virtual robots visible to the network.

Windows Firewall
You should disable the Windows Firewall to establish a UDP connection.
WSL2 on the Same Windows Machine
Set WSL2’s networkingMode to Mirrored instead of NAT, otherwise, UDP packets sent to ROBOGUIDE on the same machine will be blocked.
