Hello amartlk,
please provide more information. Did you ping the IP-adress or the DNS-name of the computer? If you've pinged the DNS-name, please try to ping the IP-adress and tell us if this works. If you can't even ping the IP-adress, please tell us more about your network, a short draft would be useful. Markus |

Hi,
I found this (they say homerouter, but it is similar to your network) http://www.gentoo.org/doc/en/home-router-howto.xml and http://www.stanford.edu/~fenn/linux/ Another point, I think that you question is more related to "Network" than to "Linux-newbie", I'd recommend that you use the report-Button at one of your posts and ask a Moderator to move this thread to the "Networking"-Forum here: http://www.linuxquestions.org/questi...-networking-3/ Hopfully this will help you.
