In your example then is the 192.168.2.0/24 network one that you changed the Zyxel LAN to before applying bridge mode?
That's right. 192.168.2.0/24 is the EdgeRouter <-> Zyxel network. 192.168.1.0/24 is my home LAN.
I've not looked at the Edgerouter yet but I've got the ER-X-SFP with 5 ethernet sockets and an SFP, so I don't actually mind using two interfaces for the time being as everything else is hooked up to a separate switch. I wanted to get my workflow for the Zyxel sorted and then I'll start configuration for the ER.
They are very similar devices, the ER-X SFP and the ER PoE. Yes, of course you can use two interfaces but I wanted to reduce clutter
And you don't really gain anything by using a separate interface for management and stat collection.
Having done bridge mode for so long with the Speedtouch, triggering bridge mode from the web UI causes me to lose all LAN connectivity to the web/telnet interfaces so I was unable to change any other settings. I am assuming that this will be the case with the Zyxel too.
Sort of. With its default interface grouping (all LAN interfaces in a single group), in bridge mode, you can connect to the router on any of the ports as long as you are in the same subnet. Which is why I have to masquerade behind the WAN interface (eth1 in my case) on my ER PoE.
Per the guide for the VMG834, once it's in bridge mode, how do I then do:
- 5. Getting line stats from the Modem when in Bridged Mode
- Configure VMG8324 access from the LAN to get line stats
... if I don't have access to the LAN interface?
This is what my configuration allows you to do. The other option is to follow the guide and adapt it to the 1312 and use two separate cables; one for the bridged connection to the VDSL modem and another to the 'default' interface group (any port in that group) for management purposes.
Or is bridge mode not required if I use separate interface groups?
Here's an image of what I see under interface groups once I've created a "bridge" group... https://drive.google.com/file/d/0B9Jjnxwtx3O4bGItMXVaUEJNa0k/view?usp=sharing
Slightly different to http://www.kitz.co.uk/routers/zyxel_VMG8324-B10A_bridge.htm
You need bridge mode if you want to use the device as a pure modem (no routing, no firewalling, no wifi and so on). How you then configure your interfaces to manage the device is up to you.
But you are right, that screen does look different from the 8324. When you add a new interface group, do you not see the same options as shown in the guide?
