ich nutze Linux schon seit '97 und habe immer wieder Netwerke eingerichtet. Irgendwie komme ich jetzt aber nicht weiter. Ich habe mich schon durch fast jedes forum durchgekämpft und viele Versionen ausprobiert. Mein Linux PC verteilt IP Adressen für das Ethernet und das Wifi mittels DHCP und hostapd. Meine Geräte (Tablet) können sich auch im Wifi anmelden, requesten Daten (kann mittels tcpdump getrackt warden), bekommen aber nichts zurück. IP forwarding habe ich aktiviert, die Firewall eigentlich auch gesetzt. Es tut aber nicht, selbst wenn ich die Firewall deaktiviere. Bin langsam echt am verzweifeln.
Hat vielleicht jemand einen Tipp für mich?
