Sinds gisteren ben ik begonnen met het installeren van een router met als basis Slackware 10.0. Alleen wil het helemaal niet lukken en ik heb geen idee wat ik fout doe.
Dit de situatie:
Zo moet het netwerk er dus uit komen te zien. Na het de Linux Networking HOWTO en de Linux IP Masquerade HOWTO te hebben doorlopen kwam ik uit op deze configuratie:
/etc/rc.d/rc.inet1.conf:
/etc/resolv.conf:
/etc/host.conf:
/etc/hosts:
/etc/rc.d/rc.local:
/etc/rc.d/rc.firewall-iptables:
Voor de verbinding tussen mijn modem en de router/firewall gebruik ik The Roaring Pengiun PPPoE software.
Het probleem is nu dus dat het totaal niet werkt. Ik kan niet eens een andere computer in t netwerk pingen. Alleen de loopback interface en het ip adres van de computer zelf zijn te pingen, maar dat lijkt me eigenlijk ook vrij logisch dat dit wel lukt. Maar nu is mijn vraag dus wat doe ik fout, want ik kom er echt niet aan uit.

Laten we maar wachten totdat de TS uitsluitsel kan geven.
