RUTXR1 as mobile passthrough as well as AP

Thanks so much - this is the reply detail I was hoping for (mostly)!

Got it

  • two cables required for AP and WAN functions.
  • zerotier can’t function in passthrough mode (though I have seen other topics here that say the lan continues to operate in passthrough and bridge modes - see Differences with Mobile Modes (NAT, Bridge, Passthrough) - #6 by Daumantas).
  • RMS remote access should still function in passthrough mode? I’d really like to still be able to access webUI of teltonika.

eth0 and eth1
So that I make sure I understand the logic, when you say

The above can be achieved by creating a new interface, configuring it by disabling DHCP and enabling Bridged interfaces , you’ll also have to select the networks to bridge between in the settings seen below:

and your screenshot shows eth0 & eth1 selected, does this mean that on the RUT, we are bridging the mobile port (eth0) and the wifi AP port (eth1), or bridging the lan to those ports? This seems like strange logic to me, since the eth0 carries the singular passthrough IP, while the eth1 port carries the AP clients to the mikrotik LAN, with very different subnets. I would have thought that eth0 would be excluded here.

I’m also wondering, with that interface created (under LAN?) does any Wireless SSIDs configured just automatically associate to any LAN interface, unless bridged - as you have specified?
