For some reason I'm having some site pestering my LogMeIn account with a bad login. It is consistently the same IP. Rather than relying upon LogMeIn's rudimentary login security I'd rather entirely block that IP entirely. How do I do that using Windows Firewall?

Open Windows Firewall with Advanced Security by running wf.msc. On the left, select Inbound Rules, then under the Action menu, choose New Rule.

  • On the Rule Type page, choose Custom.
  • On Program, choose "All programs."
  • On Protocol and Ports, leave the default of Any.
  • On Scope, select "These IP addresses" in the remote addresses section and add the problematic IP address in the Add dialog.
  • On Action, choose "Block the connection."
  • On Profile, leave the defaults of everything checked.
  • Finally, on Name, give the rule a name and optionally a description.

  • @greenber It's one of the steps in the New Inbound Rule Wizard that appears once you select Custom on the first (Rule Type) page.

I found the steps given in the correct answer work today, once again thanks. But not intuitive to follow in the Microsoft firewall wizard. Another more scaleable but still not intuitive way, is to use an elevated powershell console.

New-NetFirewallRule -RemoteAddress 192.168.100.42 -DisplayName "Block Remote 100.42" -Direction inbound -Profile Any -Action Block
