Hi All,

I have a home office and I share the internet connection with the rest of my family at home.

I am going through the PCI compliance process and find that I need to split my office PC’s from the home PC’s so that the PC’s used to process card transactions in my office cannot be accessed from the home PC’s.

I thought I had an answer but this does not appear to be sufficient, can anyone advise me please?

The setup I have tried is as follows;

I have a gateway router which is set as a DHCP server, I set this to allocate IP addresses in the 192.168.1.0 range and all my office PCs and Printers are connected to this router via fixed cat5 cables.

My home router is connected to the gateway router via cat 5 cable and the home router is set to allocate IP addresses in the 10.0.0.0 range.

All my home laptops and my home printer connect to this router via WIFI.

As I said earlier I thought I had the answer as it seemed to make two separate networks whereby the office PCs could no longer be seen in the network on the home laptops.

BUT it seems that we can still print from the home laptops to the office printer which means there is still some connectivity between the two networks.

The equipment is
Office Router = Technicolor TG582n
Office Printer= Samsung CLP-620
Home Router= Netgear WNDR4500
Home Printer=HP Deskjet F4500

Any help or advise would be welcome, and thanks to anyone who takes the time to try and help :o )

Cheers

Are the home wireless devices for sure connected to the netgears wireless and not technicolor? Also when you run the wire from the gateway router to the home router do you go into the internet port? You have to go into the wan port so the networks can be seperate and the firewall can do NAT for you.

Hi Thent,
Thanks for taking time to try and assist me. The wireless on the technicolor is disabled and the cat5 to the home router is in the internet port. Are you suggesting it should be in one of the lan ports instead?
Cheers

I am going to take a guess here at what is happening. I would reverse the networks have everyone in the house connect to the gateway and hang your network behind the 2nd router. something is letting data between the networks. Is the printer in your office wireless by any chance that could do it..
