Thanks for everyone’s responses. I have managed to solve it and here is the process:
- Create a host entry in the firewall for the server that cannot connect to the ESET network.
- Create a Filter in the Proxy content Filter and allow access to everything.
- Create a profile in Proxy content Filter linking the host server (1) and the allow all (2).
This allows access to the eset servers for licensing etc.
Hope this helps the next person that has an issue.
