Can access web from clients but not server
I have a Debian stable box set up that acts as my firewall/DHCP/router/web server/samba file sharing wonder-box.
I can access the web from any client connected to the server, but if I SSH to the server and attempt to make the server update software I will get an error that the connection has timed out. Trying to ping sites while SSH'd to the server will also result in errors.
The machine has two network cards (1 to the cable modem, 1 to my network switch). At one point in time it did work properly, so I have no idea what changed to make it act this way.
