General Router FAQ Using the Vigor 100 / 110

If you have a router with Ethernet-based WAN ports, you will often want to get a public IP address to it, even if you have only a single public IP address from your ISP. The same may apply if you have a PC which needs a public IP address. You cannot use a standard router for this, as it will need to operate one-to-many NAT in order to give each IP chain component a unique IP address.

By using PPPoE, you can get let your ADSL device look after the ADSL line (modem sync. and ATM layer) but pass the raw data straight through to your router/PC which can then look after the PPP login and ISP authentication itself. In this way, your router, not the ADSL device gets the public IP address(es) for itself.

Setting up your ADSL Ethernet Bridge (Vigor 100)

The Vigor 100 comes pre-set for most UK ADSL lines and with VPI/VCI set to 0/38 which is used by almost all ISPs. Therefore, no setup of the Vigor 100 is required normally. It does not store any Internet usernames or passwords itself. Just connect it up:

Connect the RJ-11 port (marked 'ADSL') on the Vigor 110 to the ADSL line (normally via a microfilter/splitter). Connect one of the RJ-45 Ethernet ports (marked LAN 1,2,3,4) on the Vigor 110 to the WAN ethernet port of your router (or PC)

If you want to check diagnostics of the Vigor 110 (to check ADSL line status, for example), it does have a web interface at http://192.168.1.1 and also a telnet interface. From the web interface you can also change the ADSL line parameters, but only do that if you know that you require specific settings, different from the defaults. There is no username or password to access the web interface and it is only accessible from the LAN interface (not remotely from the Internet).

The screenshots at the bottom of this page show how you would now set up various routers/devices for the Vigor 100 or 110:

Setup for 'BeThere' (UK ISP)

The Vigor110 modem comes pre-configured for all ISPs apart from BeThere/O2 which uses unusual line settings (MPoA instead of PPPoA and different VPI/VCI settings). To configure the Vigor110 for BeThere, follow these instructions:

1. Connect the power adaptor to the Vigor 110 and turn it on.
2. Connect an Ethernet cable directly from a PC to the Vigor 110.
3. After a few moments, the PC should get an IP address (Most likely 192.168.1.10)
4. In your web browser, access the Vigor110's web interface at http://192.168.1.1
5. Go to the Internet Access menu and then click on the MPoA tab.
6. Check that the settings are correct (VPI 0 /VCI 101/1483 Bridged LLC)
7. You must now click the 'Enable' button on the MPoA tab.
8. If you wish, you can also set the modulation mode (e.g. ADSL2+) but this is not necessary, it just makes it re-connect quicker.
9. Do not select Annex M unless you definitely have that from your ISP.
10. If you are unsure, leave the modulation at AUTO; it will work just fine.
11. Click OK and the Vigor110 will save the settings and reboot.
12. Connect the ADSL line cable.
13. After a short while* your PC should then get a new IP address which will be the public IP address allocated by your ISP.
14. You can access the Internet normally :-)

*This short while can vary considerably when swapping devices on your line as BeThere take a while to 'forget' about your current equipment and access a new MAC address. This has been observed as up to an hour, but can also be minutes.
