I have a problem and am looking for a solution to prevent it. The issue is that I have an IP printer, which is fairly old, ~5 years old, and it keeps on getting "toner bombed" from people in Serbia. What we want to do is somehow hide this printer from specific IP addresses or somehow only allow specific addresses through.
What can we do? We still need this printer available online, but we need to somehow restrict its access a little bit.
