Hi all,

For some reason i cant seem to ping outside my local network?

ping xtra.co.nz //always times out?

I have tried from different PCs/Window/Linux. Are there settings i need to change in the router?

Thankyou for the help

xtra.co.nz blocks pings

try pinging www.orcon.net.nz or www.google.co.nz

Your router may be blocking outgoing icmp requests.

Have a look at the firewall on the router

Haha thanks Sounddude.

So google and orcon work.

But I just pinged my home ip from work and nothing?

The reason for this is that i want to ssh into my home box, I have forwarded the port but it does not connect, i figured if i cant ping my ip theres no way i can ssh in.

Thanks

most dsl routers block incoming ping by default.

There should be no reason why your SSH forwarding doesn't work.

Unless he set it up incorrectly :)

ICMP and SSH are quite different so thats probalby not the best way to go about troubleshooting. You best bet for basic connectivity testing of most TCP based services quickly can be to try telnet to the listening port.

Useful site for trouble shooting (not that it is its primary purpose) is Shields Up!

It allows you to scan for open ports on your firewall. Of course is primary purpose is to find ports that you have left open that you did not intend to.

Being able to ping your firewall would be very bad from a security standpoint because it lets people that are looking know that you are there.
