This is different than most of the other questions I've researched so far. My Debian server can access and be accessed on the local area network only. It cannot ping the outside world. It can ping the router, and can perform cached
nslookup's without a problem. When trying to do a
traceroute 18.104.22.168, it cannot connect to anything.
If I do a
ping www.google.com, I get the IP address, then all packets lost. I can ping my router, and my notebook from the system. I have tried restarting networking, and verifying the
/etc/network/interfaces file. Name resolution is not an issue (as most others were), and this is not running a GUI. Currently, I am SSHing into it from my notebook. All other devices on my network can access the Internet. My Debian box is not an edge device, it's completely behind the router. What can I look for next?
