AHA! It was a silly mistake of mine. I didn't remove the brackets for the nserver, users, and allow parameters in the 3proxy.cfg... but I did leave them for the proxy IP addresses at the end.
Maybe make a note to not include the [ and the ] for us newbies.
It took a while but it finally works atleast for the main ip address. My additional 4 IP addresses I purchased still defer to the main IP address on the whatismyipaddress.com website. Maybe this is an issue with the VPS provider tech support?
At anyrate, I made it this far so @aleks93ts @dwayne @krafteg and everybody else who contributed to this thread, thank you!
