Topic: IPoE protocol support ?

The content of this topic has been archived on 30 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.


I try to connect my adsl line, but I guess my ISP uses the IPoE protocol, and I cannot find it as a choice for the wan interface.
Does openwrt support this protocol ?
Does it depend on my modem ? (TPLINK WR841N)

sincerely yours

Uhm, IPoE essentially means IP over ethernet, so most likely simply DHCP.

I think it is the same, but as DHCP didn't work, so I thought (hoped) IPoE was a different thing.

Also DHCP didn't work maybe because I haven't got the good parameters ("Client ID to send when requesting DHCP";  "Vendor Class to send when requesting DHCP", "Hostname to send when requesting DHCP").
I asked The ISP (Bouygues telecom) tech support for these parameters, they answered "we don't know, and we cannot reach those who know"

IPoE seems to be a short name for IPoEoATM, also named RFC1483 bridged, handeled by  br2684ctl module.
So I installed that module, and tried to enable such a connection, without any succes yet

I edited /etc/network/config with :

config atm-bridge
option unit '0'
option encaps 'llc'
option payload 'bridged'
option vpi '8'
option vci '36'
option atmdev '0'

config interface 'wan'
option ifname 'nas0'
option proto 'dhcp'

(vpi/vci are those known to be used by my ISP)
but connection doesn't work...

If I try to create the ATM bridge by hand, I get :

root@OpenWrt:~# br2684ctl -c 0 -e 0 -a 0.8.36
br2684ctl[2807]: Interface "nas0" created sucessfully
br2684ctl[2807]: Communicating over ATM 0.8.36, encapsulation: LLC
br2684ctl[2807]: Fatal: failed to connect on socket; No such device

Any idea ?


atm is for dsl modems, not ethernet routers.

right, but the TP LINK WR841N is a modem + a router

lol where did you read that???

That model definitely contains no DSL modem.

I got confused, as it supports PPPoE & PPTP, I thought it was a modem.
Thanks for the enlightment !

Hi stout.

How do you use the internet connection now ? What is the hardware used to connect ? ( brand/model of the modem )


My ISP transmits Internet and TV by Vlans. The internet service is to Vlan 10 and autentication/protocol is PPPoE, and in Vlan 20 provides de IPTV, however, the autentication/protocol of IPTV is IPoE.

I don't got it, how I can set IPoE in this OpenWRT. Is it possible ?
Can I install like a package of this service (IPoE) ?

I am looking forward ...
Thank you
