Vigor 120 ADSL Ethernet Modem
- ADSL, ADSL2 & ADSL2+ Ethernet Modem
- Bridge (pass) a single IP address or a whole public subnet
- Ideal Partner for DrayTek dual-WAN products
- Ethernet Connection for client device (router, PC etc.)
- ADSL Parameters pre-set for UK parameters (adjustable)
- Normally no setup/configuration of the Vigor 120 required
- Annex A & Annex M
Note: The Vigor 120 supersedes the Vigor 100/110
The DrayTek Vigor 120 is an ADSL modem with an Ethernet
connection; it is not a router but a true ADSL Ethernet Modem. By
providing a PPPoE to PPPoA bridge, the connected device (firewall,
router or PC) can log into the Internet (your ISP) directly and have
full control over the ADSL connection - that makes the Vigor 120 a
unique product. You can connect any device to the Vigor 120 which has a
PPPoE client facility, which includes PCs, most Ethernet-WAN routers and
the Apple Airport™ but the actual connection to your ISP is still PPPoA
(unlike other modems which only provide PPPoE native bridging), which
is the unique feature of this product and makes it compatible with all
UK ISPs, where PPPoA is used as standard.
Other ADSL Ethernet 'modems' use workarounds to get a public IP address
'through' to your secondary device/client, requiring non-standard
operation and complicated dual-stage setup (modem logs in, router
routes) but the Vigor 120 provides the secondary device with a real
routed IP connection and the ability to fully manage the connection,
making setup easy. In most cases, the Vigor 120 needs no setup or
configuration - just plug it in and set up your PC or router. All
login/ISP details are entered on the connected client device, not the
This method also differs from using a regular ADSL router which logs in
itself and then uses NAT or multiple public IP addresses to create an
onward client connection for your secondary device; that is not IP
Address thrifty, or introduces secondary NAT compromises. With the Vigor
120 bridge/modem, you get a true single public IP address (or multiple,
if you have them) straight through to your firewall/router, which also
has complete control of the ISP connection.
