Hello,
My current set-up is as follows:
FTTC internet -> openreach modem -> Draytek 2830n -> video conferencing device that hates NAT and routers in general (the only device on the network as it's a dedicated line)
The device needs to be public and needs to not have any routing in the way. The Draytek 2830 does not allow TrueDMZ or bridging on WAN2 port, which is the one that is used to connect it to the Openreach modem.
The problem with the video conferencing device is that there's nowhere to store connection username and password, so I can't connect it directly to modem, which would be perfect. My question is: what is the best way to put this device as a public device on the network so that it isn't subject to any routing? I want as little infrastructure as possible and as close to this device being connected directly to modem as possible.
Thanks

According to page 134 of the user guide here you should be able to set it up as a DMZ host. Does that not work?

Block of static IP addresses from the provider and run router in NON-NAT mode
Or change to a bridging mode router, than can pass on the PPPoE delivered IP address via a DHCP request. Was a more common mode in ADSL2+ modem/routers than pure Ethernet routers.

Nope. The device gets packet loss. Simple DMZ never worked on it, only 'true' DMZ which I can't set-up on WAN2 port
|

Do you know of any such devices? Given that all I need to do is pass all of the traffic to the device, surely there must be something simple that I can buy? I also considered using a PC with 'untangle' software as a router, but that seems a bit unnecessary? Surely I don't need to run a PC just to pass all traffic to the device?

Off the top of my head NO.
http://www.akadia.com/services/zyxel_transparent_mod... suggests that Transparent mode that is on some Zyxel kit might work.

I think an unlocked bt hg612 would do what you require.
|
|
|
|
So the unlocked firmware would allow me to enter my connection log-in and establish the connection to the ISP without a router?
|
|

After unlocking the HG612 you can configure it as a combined modem/router, which is what it is, like we were all used to on ADSLx. The locked one is configured in bridge mode.
Whether that is suitable for your needs I don't know, but costs nothing to try.
Long thread about it. The OP was the first here to try it, and succeeded. A few since have followed him.

Certainly sounds like something that could work. I am not an expert, but I remember in ADSL2+ days, you could use the bridge mode ('modem only') on routers with the modem doing the logging in, so I used to bridge the video conferencing box to BE Unlimited, where all the BE box was doing was logging in and functioning like a modem. I don't suppose the HG612 will have this mode? If I put the HG612 out of the bridge mode, then I'll probably have to deal with their NAT, port forwarding, etc., but that's one device less so can't see it being worse than the current set-up!

The only other annoying thing is that both my modems are ECI Telecom. Couldn't find anything about unlocking this one online, so I assume I'll have to get an unlocked HG one from ebay or something.

The ECIs can be unlocked but it it involves opening them up and messing with the hardware. Buying an HG612 off eBay is the best bet. Make sure it's a 3B model as earlier ones could overheat. It's identifiable by a white power unit - earlier ones had black. Unless someone cheats.

if you search for 'hg612 pdf' you should find the full user guide for the unlocked version
|
|
|
Unlocking is easy and the locked versions are often cheaper than those that are unlocked.

Thanks guys, bought one now, hope it helps me!

Can your video conferencing device create a PPPoE connection?
|
|
|
Unfortunately not, so I won't be able to just bridge it to the HG612, but I am hoping that getting rid of one of the devices (the Draytek) between the video conferencing device (Polycom HDX) and the internet will help the connection anyway. It will also give me something new to play around with as I have exhausted all options on the Draytek, the router is far too complicated for what I need and has too many options.
I assume I can't get the mode where the HG612 functions as a modem only, but also logs into the ISP? It used to work really well with BE Unlimited. Back then, I used to just hardcode the public IP into the Polycom and that was that. Their box used to have a bridge mode (or modem only mode) that also did the logging in. Or was it the case that they didn't need to log in at all? I can't remember. But that used to work much better than what I am getting right now on whichever of the hundreds of setting combinations that I have tried.
Thanks again.

Pity. I think you should be able to get the HG612 into half-bridge mode to pass the IP address to the device. The help menu in the settings is quite comprehensive.

I've used Polycom HDX on ADSL lines in DMZ mode with a number of different routers with no issue - it can be done!
 Comms is hard |
|
|
|
Yup, it was fine with simple port forwarding on Draytek 2700 on ADSL2+, so it can be done on some set-ups, but clearly my set-up isn't one of them.
|
|
|
|
By the way, does anybody know if it's possible to fix LAN port speeds on the HG612 to 100 full-duplex or are they auto-negotiation only? I've been googling but I couldn't find it!
|

Works great, thanks guys for this great, cheap solution! 
Received my HG612 today, unlocked it plugged the Polycom into LAN 2 port, set it to DMZ and it works great!
Quick question: If I need to add more devices to this network, do you think it would be a good idea to add just a simple network switch and plug it into LAN1 port, or would I need anything more complex?
Thanks again.

If I need to add more devices.....
Should be OK to do as you say, Is it performing DHCP?
Make sure you run a shields up scan grc.com/x/ne.dll?bh0bkyd2
Most ports are only closed not full stealth....more details on the grc website.
You may have to forward some ports to stealth them (some may be open ).
