How do I connect a CH6640E cable modem from Kabel Deutschland in bridge mode with a TP-Link WR842N V2.3 openwrt router running Chaos Calmer? I connected the wan port of the openwrt-router with the lan1-port of the cable modem, but I don't get access to Internet. What do I have to do?

you log into OpenWRT go to NETWORK/ INTERFACES/ GO TO WAN EDIT/ CLICK ON PROTOCOL DROP DOWN WINDOW .Their should be PPP,PPtP,PPPoE,PPPoA,L2tp,OPENWRT HAS A NEW PACKAGE PPP-multilink A PPP (daemon with multilink support) and PPP-mod-radius.If you have none of these thin you don't have the packages installed you will have PPPoE.Call your ISP and ask with protocol you need to bridge your modem with a router,click on to it if you don't have it install it put your click on switch protocol put in user name and password you are ready to go.My protocol is PPPoE i have no problem with IP6 if you do IPv6 Tunnel Setup with Sixxs

Install aiccu and the required dependencies:

by default your provider modem(Router) is in normal router mode. If you want  the bridge mode you have to setup this on Vodafone Website login and search for the router settings and change it to bridge mode after this change the router get a firmware upgrade its take 15 min up to 24h

Then the LAN 1 port give you now the ip over dhcp, this is the openwrt default for WAN. bu you get only ipv4 no ipv6

Correct. Kabel Deutschland is PPPoE

Unnecessary.

N.B. the first sentence of the thread.

@tristank: Some cable ISPs (charter for example) require you to power cycle the modem and the router (simultaneously) before delivering DHCP addresses to the router. Ex-Kabel Deutschland, now vodafone, might behave similarly. My best guess is that in the luci GUI the default protocol DHCP should be the correct one.

        @ckm & @ Max: Vodafone uses PPPoE on its remaining DSL-lines, but I would be really amazed if they would use this on their DOCSIS plants (as that would be a sort of belt and suspender approach to user authentication); heck even Max's link seems to confirm that... (The link is to a question which PPPoE (username & password) settings to use with vodafone with the response "No settings required")

DOCSIS + PPPoE

I am not saying that DOCSIS is incompatible with PPPoE or that it would be impossible to use PPPoE over DOCSIS; I am saying that Vodafone does not seem to use PPPoE on its DOCSIS plant, so from OPs perspective the pppoe subthread seems like a distraction. Thanks for the link though.

I never seen a cable based internet service that uses PPPoE, its either Static IP or DHCP, which is binded to a MAC address.

Thanks for all answers. It seems that powering the modem off and back on after a longer period of time has solved the issue. I also had to make sure that the only device connected to the modem was the router, because for some reason that MAC-Address is than whitelisted for use by Kabel Deutschland (Vodafone). There are no PPPoE credentials necessary.
