After upgrading to 26.7.1 none of the Aliases defined are working correctly in the Firewall rules eg

Internal_DNS_servers alias defined with multiple IPv4 and IPv6 addresses

Rule allows Internal_DNS_servers to make any DNS connection UDP/TCP

Later I have another rule which blocks non DNS servers from making external DNS queries

Rule blocks !Internal_DNS_servers to make any DNS connection UDP/TCP

My internal DNS servers are being blocked on the second rule

Tried upgrading to 26.7.1_1 no change in operation


Looking at the forum post below, there was a suggestion that removing the underscore might be a resolution, tried removing all the underscrore characters from my aliases and applied the update but the problem remained.

Upgraded to 26.7.2 this evening, disabled my allow all traffic rule and immediately the DNS servers DNS queries were being blocked.
The current single DNS_NTP_Server alias which consisted of each server IPv4 and IPv6 address was replaced.
Each DNS server had a host alias created consisting of its IPv4 and IPv6 address, then a DNS_Server host alias was created consisting of each DNS server host alias. Editted the existing firewall rules to replace the old DNS_Svr host alias with the new DNS_Server Host alias. Disabled my allow any rule, the DNS Server traffic was being blocked. Tried disabling the block !DNS_Server rule to see if the traffic would be allowed but it was still blocked, it is as though the DNS_Server all DNS traffic rule was being ignored.
