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.
