Ok. The problem is that you have a route to your network, but no gateway 
route. See my route -n output for comparison:

$ /sbin/route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
10.0.0.0        0.0.0.0         255.255.255.0   U     0      0        0 
eth0
0.0.0.0         10.0.0.1        0.0.0.0         UG    0      0        0 
eth0

I think the root cause of your problem is that your router and your 
network have the same IP address. Subnetting reserves the address with 
the host bits all set to 0 (in this case, 120) as the network address.

Bump your router's internal IP address up to 209.112.193.121 (and adjust 
its DHCP server settings accordingly) and see if that fixes your problem.
