Hi @muzicman0 

Thanks for posting in our business forum.

Do you use ping to verify that there is a small no response while you are editing the gateway ACL?

Try to ping the default gateway to see if there is a small drop. If you ping other devices, make sure they are wired to the router before you run the tests.

In my past experience with the gateway ACL, it should not have a noticeable drop. It should reapply the settings while you edit that. But basically should not be noticeable.

  @Clive_A Thanks for the reply.  In the 2 cases I have seen this today, I was outside the local network (using my VPN from home - but not one of the Omada VPN options, we use Tailscale) and my connections were disconnected every time I hit apply when changing a rule.  I was no longer able to connect for at least 1 minute.  So I am not sure if it is only incoming connections?  

Tailscale.. I don't have a comment on it. It could reestablish the incoming connection. I don't recall experiencing anything like this when I changed ACL in LAN.
