Raspberry Pi utility/program to find its external IP address

I prefer common sense.

You remind me of the person who asked 'why don't they stress airliners to 10g?'

The answer being that the pilots have already passed out at 5g.

Back in the day one of my engineers went to do a security check on a company who had just installed a firewall.

They asked him 'what is the most serious threat you found?' The answer 'all the auto answer modems connected to staff computers so they can access them from home, and the list of passwords pinned behind the receptionist where any visitor can see it'

Deal with the really likely threats, first.

Do you leave your front door open because your valuables are stored in a safe?

when it comes to internet security your router is your front door, if that is not secure you are exposing everything else to risk (The Auto answer modems & Passwords lists are the equivalent of leaving the bathroom window open).

NO, I leave it open because there is no crime here and I have no valuables. And its lockdown

Straw man alert! Straw man alert!

Er no, they are the front door. The router is in fact a trapdoor to a blind cellar with one drain leading out of it.

I see you didn't read Kettlewell's piece.

?It is not the truth of Marxism that explains the willingness of  
intellectuals to believe it, but the power that it confers on  
intellectuals, in their attempts to control the world. And since...it is  
futile to reason someone out of a thing that he was not reasoned into,  
we can conclude that Marxism owes its remarkable power to survive every  
criticism to the fact that it is not a truth-directed but a  
power-directed system of thought.?

If wampoon was a firewall under my control, it would drop all inbound packets on its external interface with a source or destination address within the RFC1918 ranges.

So drop all spoofed packets arriving at the external interface.

Yep that's one of the very early clauses in any decent firewall.

I cant see why any NAT router wouldn't do that anyway.

It should of course and I suspect nearly all do (I don't use off the shelf routers so I don't know). I think the whole point of this sideline is that NAT is not enough you need filtering too and any sane router configuration will do both. It is important to understand this if you plan to mess with router configuration.
