After any reset to factory settings you will need to make the following change using the web admin user interface in order to get the device to work properly as a straight modem. (Factory default <code><nowiki>http://192.168.1.1</nowiki></code>, and your own ip address set to something suitable in that same /24 subnet, username=admin, password=admin.)</p>
Go to “Setup” and “ADSL Setup” and there tick “Manual Setup”. Then tick “Bridge Mode”. The “Connection Type” should show “1483 Bridged IP LLC" and the VPI / VCI settings on that page should be set to VPI = 0, VCI = 38. See also article at [http://www.dlink.com/uk/en/support/faq/modems/dsl-modems/dsl_320b/how-to-setup-dsl-320b-revision-z1-in-bridge-mode bridge mode setup article at Dlink website].
If your modem is accessible by users on the LAN, see the notes on security and access given earlier. Ideally consider using your router’s firewall capabilities if possible to block access to the modem. Failing that upgrade the firmware - see earlier notes - and set a suitable administrative password (see the Maintenance menu).
<i>Performance tip</i>: the leaner PPPoEoEoA + RFC2684 [obsoletes RFC1483] section 6.2 + <b>VC-MUX</b> header option (“bridged PDUs: VC-MUX”) is always <em>more efficient</em> than or the same as the alternative “LLC” header option. Choose 1483 Bridged VC-MUX aka PPPoE VC-MUX in preference to LLC if your exchange supports it, for example if you are using a BT 21CN line or a TalkTalk line. If unsure, use PPPoE / 1483 Bridged IP VC-MUX if there are no problems, otherwise ask AA support. The actual effective speed improvement depends on the length of the packets being sent (because of the absorbing effect of ATM cell padding) and for some packet lengths the performance gain is zero.
