One may wish to use the TG582n just as a router, and use an external ADSL or VDSL modem. In your author's case, the performance of the TG582n as an ADSL modem
was found to be very poor (3.2km2 km from the exchange, 8km8 km from a very powerful Medium Wave transmitter) and a different modem was much better (part of
a modem/router which can't do IPv6...).
=For VDSL, create an interface with the appropriate VLAN=
''Text to be added shortly''
BT's VDSL runs over a VLAN (101), and the Openreach modem (now discontinued)
and other modems expose the VLAN over the PPPoE link. So a 'shim' interface
is needed on the router to cope with the vlan.
:eth add vlan name=FTTx vid=101
:eth bridge vlan ifadd name=FTTx intf=virt untagged=disabled
:eth ifadd intf=eth_PPP
:eth ifconfig intf=eth_PPP dest=eth_WAN vlan=FTTx
:eth ifattach intf eth_PPP
=Switch PPP over to use this new interface=
One can't '''ppp ifconfig''' an interface which is administratively up, so one has to bring it down first:. The ''dest'' field
should be ''eth_WAN'' for ADSL or ''eth_PPP'' for VDSL.
:ppp ifdetach intf=Internet
:ppp ifconfig intf=Internet dest=eth_WAN|eth_PPP mru=1492
Then bring PPP back up:
:ip ipadd intf=ModemLink addr= addroute=enabled
