How do I do that?<br /> <br /> <br /> ====Resolution====<br /> The Cisco 675 and 678 are very similar. After April, 2001 Qwest is distributing<br /> only the 678. The configuration of both routers is the same with one exception,<br /> which is noted below. In general anything that refers to the &quot;675&quot; in this<br /> article applies to both models.<br /> <br /> The first thing you need to check is if your Cisco came in bridging or routing<br /> mode. Many of them have been shipped in bridging mode. To find out, look at the<br /> bottom of the router. There will be a sticker with a line that looks like:<br /> Cisco675 Mode: If this is set at bridging we&#039;ll need to reset the router to<br /> PPP mode in order for it to work with SWCP. If you&#039;ve set passwords using the<br /> &quot;Commander&quot; program make a note of these. We&#039;ll need them later.<br /> <br /> Connect the blue management cable to the &quot;MGMT&quot; port on the back of the router<br /> and to the serial port on your computer. We&#039;ll be using Hyperterminal (or any<br /> other terminal program you&#039;re used to) in order to talk with the Cisco 675.<br /> Terminal program settings should be 8 bits, 1 stop bit, no parity, and no flow<br /> control. You should be making a &quot;Direct&quot; connection, not a dialup connection.<br /> Note: If you specify &quot;Hardware flow control&quot; you won&#039;t be able to talk to the<br /> router. Also note, any changes you make in HyperTerminal will not take effect<br /> until you exit and restart HyperTerminal.<br /> <br /> The first screen you&#039;ll seen will ask for a Password. That should be the root<br /> password. (The first one you set). The second password is the enable password.<br /> The initial passwords are null, so if you didn&#039;t set a password or enable <br /> password with the Commander program you can just press enter at the password<br /> prompt.<br /> <br /> To set the unit up for PPP mode we first need to flush the NVRAM. Type the <br /> following:<br /> enable<br /> set nvram erase<br /> write<br /> reboot<br /> <br /> This is take a few minutes to reboot. Next we&#039;ll set up PPP. <br /> enable<br /> set ppp wan0-0 ipcp 0.0.0.0<br /> set ppp wan0-0 dns 0.0.0.0<br /> set ppp wan0-0 login Your_Email_Login<br /> set ppp wan0-0 password Your_Email_Login_Password<br /> set ppp restart enabled<br /> set dhcp server enabled<br /> set nat enabled<br /> write <br /> reboot<br /> <br /> At this point any passwords you previously set will be gone, so you&#039;ll want<br /> to set a login and enable password. Please keep track of these!<br /> <br /> enable<br /> set password exec Your_Exec_Password<br /> set password enable Your_Enable_Password<br /> write<br /> <br /> Your router should now be routing, serving DCHP, and doing Network Address<br /> Translation. Note: by default the Cisco 675 will use the 10.0.0.0/24 class<br /> C network as your IP space. The router will have IP address 10.0.0.1, and<br /> other machines on your network will be numbered starting at 10.0.0.2 from <br /> the router acting as a DHCP server.<br /> <br /> If you have a 678 and your DSL protocol is DMT instead of CAP (all new Qwest<br /> DSL circuits after April, 2001 are DMT), then you need to enter these additional<br /> commands:<br /> <br /> set interface wan0-0 disable<br /> set interface wan0-0 vpi 0<br /> set interface wan0-0 vci 32<br /> set interface wan0-0 enable<br /> write<br /> reboot <br /> <br /> <br /> ====Related URLS====<br /> http://www.users.uswest.net/~rlutton/ADSL/<br /> <br /> <br /> ====Related KB articles====<br /> [[KB 82]] I need help setting up my QWest DSL connection.<br /> <br /> [[KB 83]] How do I install the software for QWest DSL Megabit?<br /> <br /> [[KB 94]] How does one set up port forwarding on the Cisco 675 router?<br /> <br /> [[KB 95]] How does one change the internal IP address of the Cisco 675 router?<br /> <br /> [[KB 113]] Is the Cisco 678 configured the same as the 675 for QWest DSL?</div>
