Unable To Browse Internet Using “class C” Ip Address?
August 4th, 2011 | 
Author: my IP Address range in use
IP Addr 192.168.x.x and
Subnet Mask : 255.255.0.0
Gateway : 192.168.1.1
DNS : 192.168.1.1
Every system on 192.168.1.x is able to browse , however the Hosts with IP range as in
192.168.2.x and above are not able to
there is no firewall configured, everything on the gateway is openaccess, there are no restrictions
As per IP addressing i should be able to browse internet from any host with ip range between 192.168.0.0 - 192.168.255.255

Except that 192.168.2.x is not on the same Class C subnet as 192.168.1.1 so your machines on 192.168.2.x can’t see your gateway.
You’d need to give your gateway device a second IP address (if it supports that) of 192.168.2.1…or set up a bridge/router to pass traffic between the two logical networks.
By the way…connecting to the Internet with NO Firewall? Really? Are you trying to become part of a botnet?
