It should be 0.0.0.0, it means on the 'local network' in this case. 
Should the destination be '0.0.0.0' (anything not covered by your previous
routes) then it goes to gateway '10.200.0.1' to reach that destination. 
The gateway '10.200.0.1' is on your local network '0.0.0.0' for eth0,
which is 10.200.0.0 with netmask 255.255.0.0  Your eth0 can reach anything
10.200.xxx.xxx on its local network.

this

eth0

as above, I believe you have this correct.

take this strategy... from the windows box

1. ping 192.168.3.1 (your linux box gw, private network, should be good)
2. ping 10.200.6.223 (which you said you could do, your external eth0)
3. ping 10.200.0.1 (the gateway to your isp)
4. ping 63.90.24.11 (olug's ip, then we know we can get to the net)
5. ping <dns servers> (make sure they are up, and we can reach them)
6. ping www.olug.org (then we know dns is working, everything is working!)
