Hello ! I would like to restrict access to my network for several computers. But the issue is we share the same IP Adress... How can I resolve this issue with my Netgear ReadyNAS ?I have tried to set up via SMB but it doesn't work... Thank you !!

Are these computers behind a NAT router with the NAS on a different network? Is the NAS in a different location? If the computers are on the same network, then they should be using different local IP addresses (generally starting with 192.168.x.x).

Hello Stephen B Thank you for your reply. Actually we don't have a local IP starting with 192.X.X.X but 172.X.X.XI tried to set up HOSTS but it doesn't work... I prefer not to use a password because I have several batch

Our ipv4 is 172.16.XX.XX As we share the same internet connection we have the same internet's IP adress. I don't know how it's set up nor how we are connected to the NAS... Sorry for that I am not an IT expert...

Sorry for that I am not an IT expert... Normally you have a single IP address for the internet connection, but your router will assign a unique local ipv4 address to every PC. If your PCs can be used at the same time, they can't have the same local ipv4 address. Your network wouldn't work if that were the case. If you have a Windows PC, you can see it's local ipv4 address using one of the methods here: https://www.digitalcitizen.life/find-ip-address-windows. I think that if you look at that, you will see different IP addresses for each machine. You can also see the local IP address used by the NAS if you look at it's network settings page. 172.16.x.x addresses are private (and your local addresses are also - even if they use a different range), so they are safe to post. They cannot be routed over the internet. It would be helpful if you can post the full addresses you are seeing for your various PCs and the NAS. https://en.wikipedia.org/wiki/Private_network
