I recently bought a Cisco E4200 wireless router  (4 ethernet + Wan port). 

I would like the 2wire to function as an ADSL modem only, and the E4200 will do the routing/DDNS/firewall etc.

I am on Telecom so my ADSL is PPPOA connection type.

I can connect the 2wire to the E4200 WAN port . In theory,  the 2wire should be able to pass the Wan IP (internet IP) to the E4200 via the wan port. 

But, I'm not sure how to get this working. I've tried to configure DMZPlus on the 2wire , but when I select the E4200 IP address the DMZPlus option disappears. 

I've stuffed around with bridge mode but no luck. 

 
These seem to be the relevant settings on the 2wire, but, documentation is lacking .

 

 
Anyone know how to do this? I'm not quite sure how the 'wan' port should work either. How is it different to a normal lan port?

It is no big deal, though it would be nice to use the e4200 as it has extra features (eg, upnp/ddns). Currently I just use the e4200 as an access point for it's nice wireless performance.

You might need to do a bit of trial and error with the 2wire settings but something like this:

1: Start with just the 2wire and one PC connected via LAN

2: Enable "Use Broadband IP's on LAN"

3: Disable "Routing" (note: may need to experiment with this on or off)

4: Apply/Save/Reboot

5: See if the PC picks up the WAN IP (via DHCP) from the 2wire

After you have the (half) bridging working from 2wire to PC, start working on the Cisco

1: Connect the PC to the Cisco (don't connect the Cisco to the 2Wire yet)

2: Change the network eg: if the 2wire is using 192.168.1.x use 192.168.2.x on the Cisco for LAN IP and DHCP range.

3: Configure the Cisco to get it's WAN ip automatically via DHCP

4: Save/Apply/Reboot

5: Connect the 2wire from a LAN port to the Cisco's WAN port

6: Go into the Cisco admin and refresh the WAN connection, check the status.

Thanks for the info.  

I tried to get this working via the pc first.

When I try to uncheck 'bridge' mode, I get...
PPPoE, PPPoA or Routed IPoA are not supported in bridge mode.

So, i ignored bridge and enabled "Use Broadband IP's on LAN" , and rebooted, checked PC, but PC is still picking up the lan address ( and the 'use broadband ip' settings have been cleared. ). 

I changed, ATM Encapsulation from "routed vc mux" to 'bridged vc mux', and connection type to direct IP, only then it allows me to deselect bridge mode. (if i try to leave connection type as pppoa i get "The selected ATM Encapsulation is not compatible with this connection type. ". 

Then i restart the router, but, it cannot log-in to pppoa because that is no longer the connection type.

From what I can tell, the modem will not support  bridged mode AND pppoa . I also tried enabling  'use broadband ip's on lan' in different combinations of the above settings but either i get an error , or , the setting does not stick.

PPPoA can't be fully bridged like PPPoE.

Alternatives that work for connecting a modem/router to a router/switch/wireless asscess point are (in order of preference):

1: PPPoA to PPoE bridge/translation
2: Half bridge via IP Extension or DHCP spoofing
3: PPTP Tunnel
4: DMZ (this is still double NAT so may cause problems for some apps)
5: WAN Bypass (2Wire controls NAT, DHCP etc, Cisco becomes a dumb AP/Switch)

I'm not that familar with the 2Wire so the the trick is in figuring out whether it's possible to do #1, #2 or #3 with the 2Wire.. otherwise you may have to live with 3 or 4.

If you have some spare time you might need to hit up the manual and docs for the unit.

Otherwise might be more cost effective/time saving to get a $60 TP Link TD-8840 that does #2 or a $100 Draytek Vigor 120 that does #1.

Have checked the manual - telecom do not supply a manual for their custom firmware. It is just the 'default firmware' manual but it does not describe what I wish to do. 

#1 is definitely not supported. 

#2 might be supported but I cannot get it to work. 

#3 beyond my meagre skills 

#4 might be possible but don't want double nat. 

#5 This is what I am doing now. It may have to be the solution. 

I was hoping to keep the 2wire --it syncs at a higher speed that any other modem I've tried (d-link/belkin/dynalink ). 

It would be nice to see if the TPLink or draytek can sync as quickly as my 2wire - maybe i'll keep an eye on trademe for a cheapie.
