Hi,

I have the ZyXEL VMG8924-B10A modem router, currently in router mode, but I plan to soon switch it to dumb modem mode with a standalone router which has only two NICs / ports. Where the phone line enters the house, I have an ethernet cable going off to the rest of the LAN, but I want another cable to terminate here to join up two separate segments of network (long story, previous home owner was a bit odd...).

I think that I can set up the Zyxel in such a way that LAN1 becomes the modem port for the router to do PPPoE, and LAN2-4 become a separate group, almost like a dumb switch (though I understand this will also allow me access to the admin interface of the Zyxel).

My question is - is an Interface Group enough, or do I need to worry about VLANs? I'm not super familiar with VLANs and don't really want to guddle with them unless I have to. From what i've read and understood so far, however, I think I don't need to worry about them - just set up a new IG with the WAN interface and LAN1, and a separate group with LAN2-4.

Any guidance appreciated!

I should add, the layout I plan is:

Phone line ---- Zyxel WAN/VDSL port

Zyxel LAN1 --- Router WAN port

Router LAN port --- Zyxel LAN2

Zyxel LAN3 & LAN4 to two discrete segments of network cabling in the house.

I realise I could just add a switch to the Router LAN port but I wanted to avoid another box / power supply in the cramped space involved. Plus I think this way the Zyxel's admin interface will still be accessible from the LAN.

Thanks!

From this, it looks like it should indeed be possible: https://kitz.co.uk/routers/zyxel_VMG8324-B10A_bridge.htm

I read your description once yesterday and then again today (twice). From my understanding of your current setup I believe that you can, indeed, configure things as you proposed in your second post.

Great stuff! Thank you

Do, please, update this thread with the results once you have experimented with the configuration.
