First thing that pops into mind is ACLs. Not sure if it will be feasible though. What's the brand of your internet modem ? – K. Rmth – 2015-06-05T06:44:22.670

This can be done - sort-of - with appropriate software, however as long as you have only 2 ports in your PC its going to be difficult to share - and someone with networking knowledge will be able to bypass whatever you do very easily. You might want to confirm if your computer uses Linux, Windows and if this can be changed. Linux is better at doing this kind of stuff then Windows, but has a steep learning curve. – davidgo – 2015-06-05T07:10:34.993
Do you have any VLAN capable (ie managed) switches you can use ? You can - in theory anyway - use a VLAN switch to seperate out your network and make it more secure. Also, is there a requirement that the IP addresses stay the same ? The "correct" way of doing this is to have different subnets for routed vs non-routed traffic. – davidgo – 2015-06-05T07:12:15.900
i dont have any switches. is there any software approach ? i can use linux if any software solution available.. ip address is not a constraint but must remain in same class – Abhigyan – 2015-06-05T07:15:53.987
