What addresses and ports on my third-party firewall should I open to allow full functionality for my ESET product?

Issue

  • Your third-party firewall is interfering with the performance of your ESET product(s)
  • You use a third-party firewall or your computer is on a network behind a firewall

Solution

Your ESET product communicates with resources on the Internet over standard HTTP protocol on Port 80, or over HTTPS on Port 443.

To resolve your issue, the following hosts in each ESET component must be made accessible:
