HILFE! Firewall fehler internet geht damit nicht
Hilfe.
Also ich habe jetzt mal mir meine eigenes ipchains Firewall Script gebaut.
Wenn ich aber das benutze, dann kann ich nichtmal nen ping nach www.yahoo.de senden.
Außerdem wird ziemlich viel geloggt.
Kann sich das mal jemand anschauen, hier ist das script, die log und andere wichtige Daten:

So, daß waren eigentlich alle informationen.
Ich hoffe jemand kann mir sagen, was das Problem ist, bzw. wiso das net funktioniert.
Die Verbindung geht übrigens per T-DSL.
Das programm ist roaring pinguin.
Bei ifconfig sind beim ppp0 device 2 Ip Nummern eingebenen.
Ich habe auch mal versucht diese p-v-p IP im Firewall script zu verwenden, das hat auch nicht geholfen.
Langsam wirds mir echt zu blöd.
Hab schon mehrere Firewall Scripte ausprobiert und bei allen gibt es immer irgendwelche Fehler, so daß die Firewall nicht funktioniert.
