You have to do the following to use the 502T as a bridge (assumes you can login to the router using the web interface and configure it). Please read this whole message before you start: 1. Setup an IP on your ethernet to communicate with the 502T. Use 192.168.1.2. 2. Login to the router admin console using a browser: http://192.168.1.1/ . The default login and password are both admin. 3. Switch the first virtual circuit (pvc0) to Bridge mode (http://shanta.linuxops.net/~raju/cgi-bin/photo/index.cgi?mode=viewpicturealbum=/Miscpicture=pvc0.pngmaxWidth=) 4. Switch the second virtual circuit (pvc1) to DSL mode (http://shanta.linuxops.net/~raju/cgi-bin/photo/index.cgi?album=/Miscmode=viewpicturepicture=pvc1.png#start_picture). Make sure that pvc1 is DISABLED. 4a. Save settings and reboot the 502T. 5. Install the pppoeconf utility. In Debian it belongs to a package called ``pppoeconf'' (apt-get install pppoeconf). 6. Now just run pppoeconf. It will discover the DSLAM or whatever MTNL equipment it needs to and create a configuration file for ppp. It will also give you options to set the default route and to start the connection at boot time. 7. Start the connection (if you haven't done so already): pon dsl-provider 8. Disable 'net access to anything in your computer: iptables -I INPUT -s ! 127.0.0.1 -j REJECT (or something equivalent) Make sure this gets done each time you start up the computer, otherwise you're at the mercy of all the l33t haxqu0r k1dd13z waiting to pounce upon you on the 'net. I don't know if the pvc1 is really needed, but it works as a backup in case something goes wrong (just enable it and set the default route on your computer to 192.168.1.1 if you have problems and you can continue to use the 502T as a router). Hope this helps, feedback welcome. Standard disclaimer: I'm not responsible if you manage to blow up your house or get your cat run over by using the techniques described in this message.

Using rp-pppoe etc., runs into issues many times. You're right, at least about the comparative complexity of using PPPoE vs routing modes. However, using PPPoE (on the host) does have the following advantages: 1. You get a routable IP and, if you really want, can expose services to your friends on the Internet. For instance, you can put up files for downloading on your Apache web server and give people the IP to download them from temporarily. 2. You control the connection. I use the 590NU (night unlimited) plan, where MTNL requires me to restart the connection at midnight and 0800. If I use the router mode, I have to physically switch the 502T off and on. OTOH, with host PPPoE mode I have a simple cron entry that does the switching (poff; pon) automagically at 00:05 and 07:58, with me blissfully asleep. 3. In general, i prefer to have control over my connections rather than some piece of hardware about which I know next to nothing. To take an example, in host PPPoE mode, the 502T is inaccessible from the Internet, and people cannot exploit any weaknesses in it. In router mode, however, the 502T is exposed to the 'net and potentially vulnerable to exploits.

Simple. then computers only on the ethernet side can connect. Infact you have a hardware firewall router sitting, which is more powerful than anything else :D regards Tanveer ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
