This is because linxu does something whihc they call ipmasquarading, but inf firewall terms is known as NAT (netwwork address translation). In short: the network card connected to the dsl-modem has an anddress of say 1.2.3.4 Your internal network has addressses in the range of 192.168.0.x where 0 < x < 255 (0 and 55 are network and broadcast address respectively). Your 2nd card in the firewall-bo would have say 192.168.0.1 (this is an unwritten default for gateways). Now, under windows setup fixed addressing and give it say: 192.168.0.10 as ip, 255.255.255.0 as netmask and 192.168.0.1 as gateway Now yout telnet issue (be sure to close telnet for the outside world though). Login with telnet on the linux box, make sure screen and lynx are installed start screen Iwht ctrl+a c you can create other screens, with ctrl+a p or n you can shift between screens (or use 0-9 for the first 10 screens) with ctrl+a d you can detatch (all lynx versions you started will keep running as long as the linux box keeps running). Whe logging in later, do screen -r and yer back were you left off. http://metalab.unc.edu/LDP/ has an exeant HOWTO on ipchains. > There are programs available to simplify the creation of firewall-rules, > but I think most are made for X, and so are hard to use. > > /Peter, who just lost his firewall due to faulty cache in the CPU > -- > Alpha Test Version: Too buggy to be released to the paying public. > Beta Test Version: Still too buggy to be released. > Release Version: Alternate pronunciation of "Beta Test Version". > > > > _______________________________________________ > > Blinux-list@redhat.com > https://listman.redhat.com/mailman/listinfo/blinux-list > slainte mhaith (good health), slainte (cheers) Uisce Beatha (water of live/health) ----------- Andor Demarteau E-mail: ademarte@students.cs.uu.nl student computer science www: http://www.students.cs.uu.nl/~ademarte/ Utrecht University irc: see webpage for details ----------- Believe in yourself, know what you want, and make it happen!
