Question about guest network setup

[amoney]

So i am running into an interesting issue. I switched from Comcast to Sail Internent. Now i no longer have a modem and my router is directly connected via ethernet to a cat 5 cable that the house is pre wired with.

After i switched i noticed my connection would intermittently keep getting reset. Sail Internet support debugged this on their end and stated that there is a mac address that is different than what is approved which is asking for a IP and thus causing the connection to be reset. The mac address in question happens to be the mac address of the bridge setup for the guest network.

What i noticed is that if i disable intranet access then the guest network gets its own bridge and when i dont it does not. So i was curious if this logic of when a new bridge is setup vs not specific to merlin code base or would the stock asus router behave the same?

Apparently sail interent logs show that a mac address that is not approved is trying to get access to exernal ip and thus causes connection reset. For now i an enabling intranet access so i can confirm that guest network bridge is the root cause.

So i was curious if this is stock asus behavior then this is some thing the ISP needs to handle or if this is merlin specific code that would be doing this. I am not even sure if i am using the right technical terms here .

Router: RT-AC88U, 386.2_2
AirMesh Node: RT-AC68U, 3.0.0.4.386_41634-g08f88ae

So update from more testing over night.

Once i enabled intrranet access to guest network i no longer saw disconnect from my ISP.

Then i also saw info in this post https://www.snbforums.com/threads/question-on-guests-network-ip-range-on-ax86.70915/ where it talked about guest network 1 behaves differently. So i tried this out. So now when i use guest network 2 and disable intranet access i no longer get another bridge network. So i think using the 2nd guest network slot with yazfi will be potential solution. I need to let this run for a bit to confirm i no longer get connection reset from ISP.

What i wanted to confirm was guest network slot 1 getting its own bridge (br1, br2 when i run ifconfig) is something specific to asus firmware and not merlin? Either way i will let Sail Internet know and hopefully they can come up with a solution on their end where folks can use #1 guest slot so they can leverage airmesh as well
