Hi, Here what I do 1°) Flash the minimal - IOT image (trixie) for Odroid N2+ on my EMMc 2°) setup Root password and user 3°) Set up locale 4°) use armbian-config to switch on kernel 6.19.0 5°) Reboot - After Reboot I can see this : v26.2.1 for Odroid N2 running Armbian Linux 6.19.0-edge-meson64 6°) use armbian-config to add linux header 7°) reboot 8°) use these commands: # grep -r "iptables" /lib/modules/. grep: /lib/modules/./6.19.0-edge-meson64/kernel/net/ipv4/netfilter/ipt_rpfilter.ko : fichiers binaires correspondent grep: /lib/modules/./6.19.0-edge-meson64/kernel/net/bridge/br_netfilter.ko : fichiers binaires correspondent # grep -r "ip_tables" /lib/modules/. -- nothing # find /lib/modules/ -name ip* lot of filkes but no ip_tables.ko 9°) use armbian-upgrade 10°) reboot 11°) retry commands grep et find: same result 12°) Try to launch # iptables -L command not found 13°) Install iptables # apt install -y iptables # iptables -v iptables v1.8.11 (nftables): no command specified # iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination # update-alternatives --set iptables /usr/sbin/iptables-legacy update-alternatives: utilisation de « /usr/sbin/iptables-legacy » pour fournir « /usr/sbin/iptables » (iptables) en mode manuel # update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy update-alternatives: utilisation de « /usr/sbin/ip6tables-legacy » pour fournir « /usr/sbin/ip6tables » (ip6tables) en mode manuel # iptables -L modprobe: FATAL: Module ip_tables not found in directory /lib/modules/6.19.0-edge-meson64 iptables v1.8.11 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. 14°) Reboot 15°) Try # iptables -L modprobe: FATAL: Module ip_tables not found in directory /lib/modules/6.19.0-edge-meson64 iptables v1.8.11 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Do I made something wrong ? Thanks

I installed the patch files with "Pb143" in the name on Friday, but unfortunately there was no improvement. Here are the logs: https://paste.armbian.com/dovedafali Can you tell me if I can test something with this? If so, what exactly do I need to do?

Did you perhaps upgrade kernel and forgot to reboot?

Module name is "ip_tables"

Thanks for your answer. I very sorry to ask you one more things please. How can I check if module is present. In modules files in "/lib/modules/6.18.10-current-meson64" ? I tried to do this : # cd /lib/modules/6.18.10-current-meson64 # grep -r "iptables" . Answer grep: ./net/ipv4/netfilter/ipt_rpfilter.ko : fichiers binaires correspondent grep: ./net/bridge/br_netfilter.ko : fichiers binaires correspondent I not an expert PS : I'am on Minimal / IOT version. Maybe it's the reason ? Thanks
