Full Bridge Mode on Technicolor DGA 4132 - PPPoE not working - VLAN issue

Nisbo · October 20, 2019, 1:46pm

Hello,

maybe its not 100% related to OpenWrt because as far as I know there is a slightly different version running on Technicolor DGA 4132 but I am new so maybe I am wrong.

This is a copy and paste from my question in an other forum

###########

Hello from Germany,

yesterday I got my DGA4132, was already rooted.
Today I updated the GUI to the latest stable version 9.4.70-184d06d3

Configuration:
DGA 4132 - Port DSL --> Internet
DGA 4132 - Port LAN 1 (eth0) --> WAN 1 to my Router (UniFi USG PRO 4)
DGA 4132 - Port LAN 2 (eth1) --> UniFi Switch (to access the GUI) <-- from my Router (UniFi USG PRO 4)
DGA 4132 - Port LAN 3 (eth2) --> not connected
DGA 4132 - Port ETH/LAN (eth3) --> There is nothing plugged in to to ETH/WAN Port on the right side and this port is configured as LAN port

I have a VDSL 250 (Profile 35b) contract by the German Telekom
The Telekom is using VLAN 7 and is also providing IPTV (Multicast IGMPv3)

Because the DGA is in Bridge Mode there should be no other conflicting options (like IGMP proxy) except the VLAN Tagging.

Regarding the recommendations in the German Onlinkosten forum I shall enable VLAN 7 tagging on the DGA and disable it on the USG (Router)
I tried it with both options for Notation: Device and Dot and did also a restart of the network

/etc/init.d/network restart

without success

After this I disabled VLAN 7 Tagging on the DGA and enabled it on the USG (router)
in this case I was not able to establish a PPPoE connection.

I disabled VLAN 7 tagging again on the USG (router) so that VLAN tagging was disabled on both devices.
IPTV was still not running but this was expected but I still had an Internet connection and this is normally not expected with a German Telekom VDSL connection.

This is how my etc/config/network looks like with "Using VLAN 7 Device"

Before I was using a "Speedport Smart 3" in Modem/Bridge Mode (there were no options for configuration) and the USG (router) was doing the VLAN 7 tagging.
This was working without problems so my favourite solution would be that the DGA is working like the old Modem ^^
So the configuration on the USG side should be fine because it was running before.

Any ideas ? Please keep in mind that I am new to DGA

EDIT:

ifconfig with disabled VLAN 7 tagging on DGA

I fixed it

Looks like the GUI did not disable the VLAN tagging correctly

/etc/config/network

in the lan part I replaced
list ifname 'ptm0.7'

with

list ifname 'ptm0'

and removed this line

list pppoerelay ''

lan part of the network config

config interface 'lan'
	option type 'bridge'
	option proto 'static'
	option netmask '255.255.255.0'
	option ip6assign '64'
	option force_link '0'
	option ipv6 '0'
	option ipaddr '192.168.178.3'
	list ifname 'eth0'
	list ifname 'eth1'
	list ifname 'eth2'
	list ifname 'eth3'
	list ifname 'eth5'
	list ifname 'ptm0'

on my router I enabled the VLAN 7 tagging

Now MagentaTV IPTV is working
