WAN and LAN over 1 utp cable

[Brainy]

Heya,

To start, i have a RT-AC87U with fw 378.54_2
In our living room we have only 1 utp cable, since our living room is in the middle of our house i would like to place my router there for the best wifi signals over the house.
In another room i have a DGS 1210-16 dlink managed switch, wich connect all our end devices (+ router ).
So my question is, is it possible to send lan ip's from the router back trough the wan port of the router to my switch (using vlan )?
If so, how can i do that?

greets
B.

Connect to your ISP provided modem to the RT-AC87U WAN port. Connect your DLINK switch to a LAN port on the RT-AC87U. Devices will get IP address from RT-AC87U with DHCP enabled. (only one DHCP Server).

Connection looks like this: modem<---->RT-AC87U (DHCP Server)<----->dlinkswitch<---->devices.

This is now the normal setup but like i said in first post .. i would like to have wan and lan on 1 utp cable :s

Well, you have to use vlan tagging and trunk port on switch and on the router then, unfortunately I`m not very familiar D-Link switches so I cannot give you any step-by-step directions.
Unfortunately on Asus router you would have to use CLI, as there is absolutely no way to configure vlan`s from GUI except for IPTV, which in this case would not help much.

But definately it would be doable, if you dig around in documentation a bit...

Perhaps you could use a pair of powerline adapters to connect your modem to the WAN port of the RT-AC87U in your living room. That would leave the "utp cable" free to connect back to your DGS in the other room.

Then you wouldn't have to create manual VLANs

ColinTaylor, that would be an option but then i lose more then 100 mbits from my modem ( i have 200 mbit and i have only 85 mbit powerlines )

Ive already tried with a setup like this:
Modem -> switch port 16 ( vlan 100 ), switch port 15 (vlan 100 ) -> port 3 router ( vlan 100 ), port 2 router ( vlan 100 ) to WAN router.
The following setup gives me a ip from my isp on my WAN side on the router but not ( yet ) back to my switch .. i need to figure out how i can have lan ip's on the rest of my switch ..
I think im very close but there is a setting wich need to be made to get it funtional, it was really late so it was bed time for me

I will suggest get another switch and place where you want Router, Create two Vlan ex 10, 20 on both switches and also create trunk port on each. Connect trunk port with existing utp cable and use two Ethernet wires to connect one two lan and wan on router, you can for example tag vlan 10 as lan and 20 as a wan, do same on other side but for vlan 20 just connect to modem and for vlan 10 you can assign all ports which have devices.

Much cheaper and faster would be to use the only network cable to put an Access Point in the living room. Buy a cheap (yet powerful/featureful) RT-AC56 to be your main router and use the AC87 as an access point.
