MAC Alias stoped working properly in business version 26.4.2?

[RFrank]

Hello opnSense community,

I've several clients where I'm using MAC Alias in my FW rules.
I did the update to version 26.4.2 last week without facing any issues.
Yesterday I add some rules with clients where I use MAC Alias inside, as soon as I stored this some former working rules where I was using this MAC-Alias in a group stopped working. Changing the Alias to Network and the IP Adress everything was working fine again immediately. But same time rules where I was using the MAC-Alias directly without using a group where not affected by this issue.
Is there a difference in using Alias directly or in group?

Hi,

We're not aware of issues with MAC aliases in 26.4.2.

What you can check is whether hostwatch service is interfering with your requirements. Disable service under "Interfaces: Neighbors: Automatic Discovery" to see if the situation changes.


Cheers,
Franco
