2. Another question I had was sometimes we don't get real physical IP of the
machine but the IP of something that's in between like "router", is there a
way to get the real IP so that we don't end up blocking people coming from
that "router" or "proxy"
In my opinion, you cannot. The whole point of such routers and proxies is to make the requests look like they are coming from the router/proxy, so that is the sender IP address you are seeing at your server level, and that's it. Your server never receives the original requester IP address.
There are legitimate reasons for this to be done as well, indiscriminately blocking such access is a bad idea as it will affect legitimate users. NAT and IP address sharing are among the reasons. This allows an organization to have a router with one public IP address to serve a larger internal network with private IP addresses. Without this, we would have run out of IPv4 addresses a long time ago.
