Telekom FTTH

configuring and OpenWRT router for Telekom FTTH.

put your router/modem/shitbox from telekom into bridge mode. unfortunately it will expose the connection as a PPPoE instead of pain ethernet with DHCP.

you need to tag the packets on your WAN port with VLAN 7.

configure

using the info from the letter you should have gotten:

username: ${Anschlusskennung}${Zugangsnummer}${Mitbenutzernummer}@t-online.de
password: ${Kennwort}
protocol: PPPoE

these examples are using a Turris Omnia router. your interface names may be different.

configure with uci:

uci set network.wan.proto='ppoe'
uci set network.wan.ipv6='auto'
uci set network.wan.username='${Anschlusskennung}${Zugangsnummer}${Mitbenutzernummer}@t-online.de'
uci set network.wan.password='${Kennwort}'
uci set network.wan.device='eth2.7'

in the config file /etc/config/network:

config interface 'wan'
	option proto 'pppoe'
	option ipv6 'auto'
	option password '${Kennwort}'
	option device 'eth2.7'
	option username '${Anschlusskennung}${Zugangsnummer}${Mitbenutzernummer}@t-online.de'
	option metric '0'
	option peerdns '0'
	list dns '${dns_server}' 


config switch_vlan
	option device 'switch0'
	option vlan '7'
	option ports '1t 6t'

note: if you enable "easy login" in the Telekom Kundenportal, you can use invalid or no credentials for the PAP/CHAP auth.
