In Germany you can get VDSL from "Deutsche Telekom" with 50 Mbit/s bandwith.

You get a Speedport 300HS Modem, which seems to be a Sphairon (

This modem expects the pppoe-packets with a dot1q-vlan-id 7. does anyone know, how to configure this?

i found this one ->

but it seems to be only for outgoing connections.

Hardware: Cisco 851 wge

Software: 12.4-15T5

I tried to configure a sub-if, but i was not able to put the dial-pool-number command on this one.

(inter fa 4.7

encap dot1q 7

pppoe enable

! commands acceptet until here

pppoe-client dial-pool-number 1

! not accepted)

thanks in advance
