Hi,

I am not sure if its the right place to ask or not, but I need some advice in sharing my home PCs and laptop, securely.

Earlier it used be plain and simple for me. I had an ADSL ISP and used to follow this setup.

ADSL used to come into TP-Link via CAT 5 with its IP being 192.168.1.1
[*]TP-Link used to have 192.168.1.2
[*]Wired PC1 running Windows 7 UL x64 SP1 with IP 192.168.1.50 used to be connected to LAN Port 1 of TP-Link.
[*]Wired PC2 running Windows 8.1 Pro x64 with IP 192.168.1.51 used to be connected to LAN Port 2 of TP-Link.
[*]Wireless Laptop 1 running Windows 7 UL x64 SP1 with IP 192.168.1.52 used to be connected with Wifi to TP-Link.
[*]Wireless Laptop 2 running Windows 8.1 Pro x64 with IP 192.168.1.53 used to be connected with Wifi to TP-Link.


I used share these 4 systems in simple work group via TP-Link without any issue.. It was secured as there was no external network (via LAN at-least) coming in..

Now the problem is, I have changed / rather added new ISP..

Which is a local cable ISP providing the Internet via LAN with its Static IP. Which is not secure at all, since sometime I can see other PCs popping up in my PC's network place :P.. Since then I have turned off network share in my all systems..

Now I need to know, how do I create a secure network share where the WAN Port should not allow any outsider to access my network :'(..
