#12052 — Getting home addresses to respond to you

So, we know that most home routers ignore ICMP requests. I've tried every 
other protocol that traceroute offers and all I get back are * * * 
responses when trying to traceroute to a friend's home IP. Is there any 
way around this to, trick (for lack of a better word), a home router into 
responding to pings and traceroutes?

Reconfigure the router.

I was afraid that was the only solution. Alright, thanks.

What other solution did you have in mind?

Absent a publicly accessible exploit hole (which, if it is a commerical
router you can't quite be sure does not exist) reconfiguring it is
going to be your best bet.

You can try an nmap scan against it to see if there is anything it will
respond to, if you really want to check.

since it is in fact a deliberate policy usually set up in the admin 
package to NOT repsond to pings, unless you create a ping passthrough to 
a machine on the far side of the router  its the only way. Of course the 
latter requires even more and more dangerous router reconfiguration.

Do they? My sample size of around 10 would disagree with that. You'll
find some routers ignore some ICMP requests, but it would break Internet
traffic if all ICMP packets were ignored.

The intermediate devices are the ones returning data (or not) for the
corresponding intermediate hops. You won't reach your friend's home
router until you get to the appropriate hop.

If you're getting nothing at all then you need to consider whether one
of your systems is dropping ICMP Time Exceeded packets (it shouldn't be).
