As that I got an old cisco router, I want to learn how to manage the network, I setup the router as the hand book write everything seems fine but some users are saying that they can't connect to specific host such as amazon.co.jp which it host ip is 22.214.171.124, 126.96.36.199 and 188.8.131.52. Don't know am I missing anything?
Can't find and part of the board can ask the question, seems that the colocation fit the most ...
I believe all have ip subnet-zero by default?
Anyway I have check all do not have no ip subnet-zero.

All setup with public ip, both 2960 3750 default gateway setup to the 7609.
