Happy to hear it! Address conflicts are always a pain, I recently ran into an issue with my VPN to my home network, where my home network and the network I was on shared the same subnet and mask, so I had to specify some custom routes to make it work. Good network design is a must to try and mitigate these things!
Performance will likely be really bad running on a live ISO since you are going to likely be bottlenecked by read/write speeds of the usb you have plugged in. I wouldn’t use it to test performance of games.
