I'll keep this post updated with any relevant UGC information.
Server IP: 152.53.194.56
RPCS3 Guide PS3 Guide: N/A but I'll try to work on one soon.
General PS3 steps
First, go to settings > Network Settings > Settings and Connection Status List and note your console's IP, subnet mask, and default router. Then Go back to Internet Connection Settings, change from automatic to custom and go through the configuration (default should be fine) until you get to IP Address Setting, select Manual. You'll need to specify your console's IP, subnet mask, router, and my server as the Primary DNS. This will be the information from the status list.
Troubleshooting
- You may have to set both primary and secondary DNS to the 152* IP. I didn't in my testing, but others have reported they had to.
- If it reports UGC Offline after you connect, try connecting again in the menu (Start > UGC > Connect to UGC) a few times. Again, not something I experienced in my testing, but people have reported it works.
