einfaches NAT für ppp über wlan
auf dem router:
cat start_nat.sh
iptables –flush # Flush all the rules in filter and nat tables
iptables –table nat –flush
iptables –delete-chain # Delete all chains that are not in default filter and nat table
iptables –table nat –delete-chain
# Set up IP FORWARDing and Masquerading
iptables –table nat –append POSTROUTING –out-interface ppp0 -j MASQUERADE
iptables –append FORWARD –in-interface wlanx -j ACCEPT # Assuming one NIC to local LAN
echo 1 > /proc/sys/net/ipv4/ip_forward # Enables packet forwarding by kernel
auf dem NAT-client:
ip route del default
ip route add default via ip dev wlanx
