Block SMB1 from WAN (but allow between PC and NAS)?

Re: SMB1 vulnerability

Is there a firewall rule that would only allow SMB1 between specific IP addresses (so i can still use an old Buffalo NAS with my PCs) and/or block SMB1 from the WAN?



Re: Block SMB1 from WAN (but allow between PC and NAS)?

Hello Chicago Area. The recommendation is NOT to run SMB1 at all, the protocol is very outdated. Here is why!!

 Windows 10 shouldn't have any issues picking up your NAS as will Windows 7. Here is an article that may help with firewall runs in your situation IF you are willing to accept the risks it will present.
