Thank you Nicolas, so what you're saying is that instead of connecting the ISP router to the switch, and then having cables from the switch going either to the wan port of LiMe routers [if they have one] or to their Lan port [if it's the only one they have], I should connect the ISP router directly to the wan port of a LiMe router that has both, such as a 1043 or a C7, and then connecting all other nodes to that device's Lan ports, or, should they not suffice, draw a cable from that router's LAN port to the switch, and then connect all other devices to the switch, is this correct?

This way, you say, only the first LiMe router receives the external DHCP. But still there are multiple advertisements. Is this not a problem any more since they are all the same, is this your point?

But still, how can all LiMe routers on that wired network have the 10.13.0.1 IP at that point though?

Thanks again

 Hi all
 
 I've finally had the chance to test out what some of you were saying
 about LiMe doing mesh over ethernet using Lan - to - Lan connections.
 
 I have a POE switch with one cable going to a UBNT AC lite, one going
 to a Bullet M2, one going to a 1043ND [on its wan port] and one to an
 Archer C7 [on its wan port]. All 4 devices have the latest images
 downloaded from repo.libremesh.org, just to be on the safe side. The
 fifth cable is going to my ISP router [IP 192.168.111.1].
 
 Since the lite and the bullet only have one ethernet port, stock lime
 configures it as a Lan port, with 10.13.0.x DHCP being handed out
 over it, and so on. So from the switch I have two cables going to wan
 ports [1043 and C7] and two going to "Lan" ports [lite and bullet]
 since that's what their default behavior is.
 
 They all mesh correctly, and even the two UBNTs serve internet
 connectivity perfectly. The problem is that when I connect to these
 two devices wirelessly with clients, I often get a DHCP assignment
 from my ISP router [as it's on the 192.168.111.x subnet] and not a
 10.13.0.x assignment.

Yes!

That is because DHCP requests are coming from your devices to your UBNT
AP, from there they move the DHCP request to the switch, and as the
request goes to the broadcast address, the switch sends the packet to
all the devices at the same time... so the one that replies faster is
the response that the devices accepts.

 I still don't understand how a network with not one, but several DHCP
 servers can work correctly.

LibreMesh DHCPs can live together because they know of their
presence... the external DHCP should be connected to one single Mesh
node.

Mesh nodes that belong to the same network (the AC Lites, the Archer C7
and 1034ND) can connect between each other through the LAN ports.

Your ISP router should be connected to the WAN port of any of those
devices.
