Just like to point out that if IP forwarding is enabled on a target host,
other hosts on the same network could access 127.0.0.1 on that target host
(or any interface for that matter).
For some target operating systems that may still work even if IP forwarding
is off.
e.g. use certain source operating systems, bring down 127.x.x.x if present,
add the route to 127.0.0.1 using gateway = target host adjacent IP. Now
ping or telnet 127.0.0.1.
Cheerio,
Link.
