Connecting two MT routers using bridged DSL modem

Mon Jun 05, 2023 2:02 am

So Let's start with this diagram. (Note that none of equipment cannot be moved.)

I have 2 rooms. In Room#2, there is a MT router (MT#2), connected by a 10m CAT6 cable as PPPoE interface to DSL modem which is in bridge mode itself and located in Room#1.
I want to connect MT#1 which is in Room#1 to MT#2 (MT#1 is DHCP client here and MT#2 is DHCP server.)
Clearly I need to wire another CAT cable from Room#1 to Room#2. However, I want to ask that can I connect MT#1 to DSL modem (using red wire) instead of connecting MT#1 to MT#2?

I heard something about VLAN but I am not sure how this can help in this scenario.

If I understand what you are trying to do, the answer is maybe. The limiting factor is if the switch in the DSL modem will pass VLAN traffic. Some switches will and some will not. If the switch that is part of the DSL modem will pass VLAN traffic, then the connection between the DSL modem and router #2 can be set up in the router as a hybrid port. The VLAN tagged would have LAN from router #2, and the untagged would be the "WAN" for router #2 and would act as the "normal" connection to the DSL modem. The connection from the DSL modem to router #1 would only be making use of the VLAN traffic, and ignore the untagged traffic.

Hi k6ccc,
Fortunately my DSL router supports VLAN, here is the config in DSL router:

Ether1 is connected to MT#1 and Ether2 is connected to MT#2
I don't know how to proceed further on MTs...

Just normal Ethernet cables. forget about CAT6 etc.
Red wire is just for better understanding. It is a networking cable as well.

DSL router is TP link TD-W8961N.
MT#2 is plugged in DSL router and other clients are connected to #2 (Shaping LAN2 together)
