Question

We have a large group of computers in our domain that use to use SEP CLoud firewall to only allow Chrome, Edge and Firefox to access a choice few bunch of websites while blocking all others. Our new Cloud endpoint service doesnt supply us with a firewall option anymore. Does anyone know how I can setup Windows firewall to only allow a select group of computers to access only a couple of Websites with Chrome, Edge and firefox while blocking all other Websites.?

Answer 1

Hello @RockmanIT ! We need also to select the Local IP addresses for the Computers that we need to block ! For the Local IP add the ranges or the IPs of these Computers so only these ae affceted by the rule Tell me how it went!

Answer 2

Hello @RockmanIT ! In case these Web Sites are Internet based you have to work with nslookup , or other tools to resolve the Ip ranges cause WIndows Firewall does not offer DNS filtering . In general here are the steps: To create outbound firewall rules that allow access only to specific websites with Chrome, Edge, and Firefox while blocking all other websites, you can follow these steps:

• Open Windows Firewall with Advanced Security.
  

• Click on "Outbound Rules" on the left-hand side of the window.
  

• Click on "New Rule" on the right-hand side of the window.
  

• In the New Outbound Rule Wizard, select "Program" as the rule type and click Next.
  

• Select "This program path" and browse to the location of the web browsers (e.g. C:\Program Files (x86)\Google\Chrome\Application\chrome.exe). Click Next.
  

• Select "These IP addresses" as the scope for the rule.
  

• Click "Add..." under "Remote IP address".
  

• In the "This IP address or subnet" field, specify the IP addresses or subnets for the websites you want to allow access to. Click OK.
  

• Click Next and select "Allow the connection".
  

• Name the rule and click Finish.
  

• Repeat steps 3-10 for each web browser you want to restrict (e.g. Microsoft Edge, Mozilla Firefox).
  

  Create a final outbound rule that blocks all outgoing traffic to any IP address or subnet not specified in the previous rules. BUT ! If you are using an Enterprise Solution like Windows Defender from Microsoft 365 then you have this option!

I created an outbound rule to enable all connection with MS Edge during which I did an nslookup and copied the IPV6 and IPV4 IP's into the field named "Allow Remote IP" for the only site that I want users to be allowed to access and then saved the rule. I then created another outbound rule to block MS Edge from accessing all websites but now when I launch MS edge and browse around all Websites seems to be blocked and I cannot access the one that i allowed. Any ideas?
