I couldn't find anything about this here and maybe its a easy thing to do but I still didn't figured how to do it yet.

I have a D-Link modem-router (DSL-2730E) configured as bridge, and a Netgear R7000, with DD-WRT, configured as router.
The IP of the bridged modem is 192.168.2.1 and the router's ip is 192.168.1.1.
I want to be able to use the ethernet ports of the bridged modem-router to connect to the internet too, instead of just the routers ports.

I tried configuring the modem-router as DHCP Forwarder but it didn't worked out, I really have no clues on how to do that! Can anyone enlighten me here? Thank's!

QoS is best managed at the gateway device. QoS on the access point would only be implemented for LAN traffic, and only for those devices connected to it.

DHCP Forwarder would be used on the Netgear (not the D-Link) via the WAN port (not configured as an access point). QoS would need to be managed at the D-Link.

You could avoid any headaches by attaching an inexpensive network switch to the Netgear to add ports, as previously mentioned.

A bridged network connection and a wireless bridge is two different things, and so I am not sure which you are meaning.

A bridged network connection just means two interfaces are tied together, which is the case for all routers or network device with inputs and outputs. A router ties the WAN port to the LAN port, and the network devices tie their input connection source to their output source.

Wirless bridge = wifi in, ethernet out
Access Point = ethernet in, wifi/ethernet out
Switch = ethernet in/ethernet out
Repeater = wifi in, wifi out.

If you are just wanting additional ethernet ports I would highly recomend just using a ethernet switch, you can find gigabit ones for $20 or less.

You can configure the D-Link modem as an access point by dissabling DHCP and setting its IP to an IP that is outside the DHCP server of the primary router. The 192.168.2.1 is outside of the subnet and that is why it is not working as a dhcp fowarder, you need 192.168.1.2 or an address outside of the DHCP server range on th netgear. As stated it would be much much simplier just to use an ethernet switch.

Thanks for your reply, and sorry for the lack of info!
The netgear router is connected wired to the WAN port, from the ethernet port of modem, and thus making the PPPoE auth. The connection type on the modem is set to "Bridged".

In this scenario, changing the modem's ip to 192.168.1.2 and disabling its DHCP would work?

The real history is that both the modem/router and the router is in the living room, and i want to be able to use the ethernet ports of both to connect all of the equipaments wired.
I prefer to not have another equipament (switch), cuz if i could use those ports, it would be enough.
And the reason why i prefer to use the modem bridged is because the QoS on the netgear is way better.
so, if i configure the modem/router as the primary router, and the netgear as a access point, the traffic on the modem wouldnt pass trought the QoS rules.

Hope i made it clear... sorry for my bad english btw, i'm from Brazil.

And if i set the modem/router as the primary router, and the netgear as access point, can i make all the traffic on the modem/router pass trought the QoS rules of the access point?

Using DHCP Forward would work?

Do not get overly side tracked by looking at the QoS function. You can really only use QoS to control the traffic you SEND to the internet ie upload. Most people are overloading their download capacity and the ISP controls that. You are extremely limited in you abilities to affect download traffic. If the ISP has decided to discard traffic you considered important there is not much you can do about it, the traffic is gone by the time your router get any ability to see traffic.

Hi, I think you may be able to do the whole setup in a fairly easy way. You can try the following:

DSL-2730E:
-Use PPPoE mode.
-DHCP On

Netgear R7000
-WAN: Dynamic IP
-DHCP On

Connect the WAN of your router to any LAN port on the Modem
----------

This way, all the 4 ports on you modem and well as router would be having internet.
The devices connected to LAN port of the modem will have an IP address of 192.168.2.X series.
Where as, the ones connected to LAN of the router will have 192.168.1.X
