Question:
Hypothetically speaking; let's say problem is solved, (or so  you're
told), and you need or want to remove this restriction, what would be
the proper or best command to reverse the process of ignoring this
particular IP address?

Would it be?:

/sbin/iptables -I INPUT -s 65.19.175.58 -j ACCEPT
 
Or, is there another / better / different way?
