Got it! The kernel is using nftables already by default, had to go for legacy support: cho@nanopim4:~$ sudo update-alternatives --set iptables /usr/sbin/iptables-legacy update-alternatives: using /usr/sbin/iptables-legacy to provide /usr/sbin/iptables (iptables) in manual mode cho@nanopim4:~$ sudo iptables-restore < /etc/iptables.ipv4.nat cho@nanopim4:~$ sudo iptables -S -v -P INPUT ACCEPT -c 76 4801 -P FORWARD ACCEPT -c 0 0 -P OUTPUT ACCEPT -c 76 14496 -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -c 0 0 -j ACCEPT -A FORWARD -i wlan0 -o eth0 -c 0 0 -j ACCEPT It works now Thx!

Hi, at first thank your for your great work! I've successfully created an wifi hotspot on nanopiM4 using "Armbian_5.95_Nanopim4_Debian_buster_default_4.4.190" with armbian-config utitlity. After the tool is finished I can connect to the hotspot and it shares the internet connection.. However - when I reboot the system the hotspot still works and I can connect but I have no connection to the internet anymore. The nonopi itself has connection to internet, I checked that. Do you have any sugestions? Thank you in andvance! Christian
