Eircom Zyxel D1000 – The most useless router on the planet

It never ceases to amaze me how our friends in Eircom are so happy to pass the buck when it comes to the terrible Zyxel D1000 especially when in Bridge Mode.

EircomD1000Its easy for Eircom to say that they do not support bridging, but the reality is that most customer want to avoid a double NAT situation.   Bridging should work, and I have found a trick that makes it work – its really weird.

On the D1000, to bridge the connection you turn off the Wireless, then the Firewall.   Lastly, you change the mode from Router to Bridge in the Broadband setup screen.    With these steps, you should then be able to configure a PPPoE session from your device, your laptop… whatever…

On 50% of Eircom D1000, the bridge might work at this point, but here is where it gets weird…….   (and this situation sometimes happens later after a power cut, or thunder storm)

On the other 50% of the devices we have setup here, the only way to make the bridge mode work is to configure it via the WAN connection (remote access).   The exact same settings as above, but over the WAN port.    <<<  this is insane, for the record.

So, there you have it.   Its on the web now, so it must be a)true* and b)helpful* to some poor person sometime in the future.

*this may be neither helpful or true

    What I found works is to first set the Mode to “Router” in Broadband settings, then change encapsulation to PPPoE, and press Apply.

    Now – change back to Bridge mode, apply settings, and it should keep the PPPoE setting, even though it’s not displayed.

    A major problem with this however is that if you lose power to the mode, it loses the PPPoE setting, so you have to do the process again – switch back to Router mode, apply etc. then back to Bridge and apply.

    A better solution is perhaps to try to use the mysterious “IPoE” in bridging mode. This probably just needs DHCP setup on the interface where you would normally have the PPPoE client attach to (i.e. ppp0 on a Linux box).

    Actually – just found an easier option for PPPoE bridging. If you set the mode to Router, then go to Advanced Setup, way down at the end of the page there’s a “PPPoE Passthrough” option.


    Set this to yes and you can run the normal PPPoE clients on connected devices in a bridge-like fashion. Also, it keeps this config after losing power.

    Yeh, I agree, it is the most useless router going. I’ve been watching BBC Click and all the wonderful things were supposed to be able to do with wifi. Not a chance with the Eircom Zyxel D1000. I rang up Eircom to see if I could get it changed and the flat answer was no. I have no control over my wifi, so it’s turned off. Just use the internet. It will not even hold a changed password. Eircom do not even update the firmware. Am about to go over to Virgin. Eircom is a carrier for Sky and Virgin is the carrier for Vodaphone, so there is no point in going with Sky or Vodaphone because when something goes wrong with the line Virgin or Eircom come out and they take their time, because Vodaphone and Sky are the competition. COMREG are toothless tigers that is why the internet service in this country is overcharged and so bad.
