PS2 LAN Party in a Box: Configuring PCSX2 for Gran Turismo 4 LAN in 2023

The GUI updates to PCSX2 have apparently changed how network emulation is configured, and I had trouble finding current documentation about how it all worked. This video describes the differences between the "sockets" and "TAP" network device types and demonstrates use of the "TAP" device by running a Gran Turismo 4 LAN game using 2 instances of PCSX2 and GT4 running on the same PC.

Note this configuration shows a *real* LAN configuration and not a VPN "LAN". A VPN setup would be a bit different, and I haven't tried it.

I wonder if a full 6 player LAN game could be played on a single high end gaming PC. Probably, but I will leave that as an exercise for someone who has access to a high end gaming PC.
