OK, now your problem seems to be clear. You didn't set up default
gateway. That's why the hosts on your network were accessable,
but nothing beyond.
When you added default gateway to your routing table you actually
told your box where to send packets destinied to hosts outside your
network.
YOu may have checked it with command
/sbin/route -n
The output should be like
192.168.104.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.104.10 0.0.0.0 UG 0 0 0 eth0
The last line describes the default gateway, which is 192.168.104.10
in my case. 0.0.0.0 as destination says that it is the default gateway.
