How can I create a special firewall rule:
There is one machine (Win7 ) blocked by firewall to red WAN.
Is it possible to create a firewall rule / firewall group to allow this machine the access right only to Avira-Update-Servers ? There are no static IP adresses for this servers ! I found this on Avira support pages:
Which exceptions must be stored in the firewall/proxy for updating?
If a firewall or proxy is active in the network and there are problems updating Avira Antivirus Pro or Avira Antivirus Server, as well as the Avira Mirror, certain exceptions should be set.
Please set the following exceptions:
The update servers are accessible via port 80.
IP addresses cannot be added for the update due to the CDN used having different, changing IP addresses.
Thank you for every advice !
