I'm using an Audience with a Startlink router. When I put the Startlink in bypass mode connected to the Audience, traffic drops to the internet every minute or so for 5 to 10 consecutive pings and then resumes. When I default the Starlink back to router mode the problem resolves. I'm able to duplicate the issue consistently. Any ideas on what could be causing this?
Thanks,

That sounds like a Starlink rather than Mikrotik problem. Can you confirm by testing with something else? Having said that I ran mine in Bypass for a while because I had existing references to 192.168.1.0. I've now removed that conflict, and had to reset the Starlink for some reason I can't remember, but I've left it in default anyway since then.

In Bypass it's still double NAT anyway since I get a CGNAT address. I'm not sure I see the harm in triple rather than double NAT. There doesn't seem to be a performance hit.

Does yours give a real routable Internet IP? That would be a good reason for using Bypass.

It sounds like an obstruction. I had a big tree in my front yard and it would drop out for about 5 seconds every 15-30 minutes depending how many leaves are on the tree.
Are you absolutely sure you don't get the drop with starlink directly?

If you don't, do you get the same results between IPv4 and IPv6 pinging? I'm assuming your Starlink has IPv6 like mine.

Even in bypass, you should still be able to use the starlink app (i.e. it resolves "dishy.startlink.com", and dishy always uses 192.168.100.1)*. The app will show drops. I believe visiting 192.168.100.1 in a web browser may do something, but they steer folk to the app these days.

Now, If "multi-wan" setup, then you need a /ip/route for 192.168.100.1 to send using the starlink ethernet as the gateway=.

In bypass you can still get statistics and obstruction and data from the account, obviously as long as the system connects to the Internet. Choose the option "Select a remote Starlink".

Maybe try this as a test to see if you still get packet drops.... https://www.youtube.com/watch?v=_7o380Rbd0o
