Firewall Advanced Packet Rules

This Article Applies to:

  • Avast Business CloudCare


Advanced Packet Rules are the final level of Firewall rule evaluation, meaning they are utilized only if the connection does not fit any System or Application rules. We recommend you ensure these rules are controlled by your Portal for maximum security across your network.

Adding Advanced Packet Rules

  1. Expand Firewall and Antivirus Add-ons, then navigate to Firewall ▸ Packet Rules
  2. Click Add Packet Rule
  3. Enter a unique name for the rule
  4. Select whether or not the rule is to Allow or Block traffic
  5. Change All protocols (256) to the correct protocol, such as TCP and UDP (257)
  6. Select the direction of the traffic the rule applies to: In, Out, or Both
  7. Add IP address (if applicable) and Local and Remote Port numbers (you may use commas for different port numbers, or a hyphen for a port range)
  8. Enter the ICMP type, if any
  9. Select what Network Profiles, between All, Public, and Private, contain this rule
  10. Click Add
    • We recommend to drag/drop the new custom packet rule to the top of the list so the local CloudCare Antivirus clients will process this custom packet rule first
  11. Click Save & Apply to Devices when you are done adding rules
    • If you are editing a Master Policy, this will say Save & Apply to Customers instead
