Freifunk-Gateway aufsetzen/keyxchangev2 VERALTET

Hier landen die ersten Infos was für Gateways bei KeyxchangeV2 geändert werden muss. Es sind nur Beispieldateien und müssen pro Hood unbedingt angepasst werden! Ungetestet!

device: bat0
iface bat0 inet manual
post-up ifconfig $IFACE up
    ##Einschalten post-up:
    # IP des Gateways am B.A.T.M.A.N interface:
    post-up ip addr add 10.83.8.1/22 dev $IFACE
    post-up ip -6 addr add fe80::1/128 dev $IFACE
    post-up ip -6 addr add fd43:5602:29bd:4::1/64  dev $IFACE
    # Regeln, wann die fff Routing-Tabelle benutzt werden soll: 
    post-up ip rule add iif $IFACE table fff
    post-up ip rule add from 10.0.0.0/8 table fff
    post-up ip rule add to 10.0.0.0/8  table fff
    # Route in die Fuerther Hood:       
    post-up ip route replace 10.83.0.0/22 dev $IFACE proto static table fff
    # Start des DHCP Servers:
    post-up invoke-rc.d isc-dhcp-server restart

    ##Ausschalten post-down:
    # Loeschen von oben definieren Routen, Regeln und Interface: 
    post-down ip route del 10.83.0.0/22 dev $IFACE table fff
    post-down ip rule del from 10.0.0.0/8 table fff
    post-down ip rule del to 10.0.0.0/8 table fff
    post-down ip rule del iif $IFACE table fff
    post-down ifconfig $IFACE down
