iptables v1.8.3 (legacy): can't initialize iptables table `NAT': Table does not exist (do you need to insmod?)

Davicom · May 16th 2021

Hi all, on my ZGemma H7s with openatv 6.4 I installed all (i think) necessary module to iptables works.

Code

root@zgemmah7:~# ls /lib/modules/`uname -r`/kernel/net/ipv4/netfilter/
ip_tables.ko               ipt_ah.ko                  iptable_mangle.ko          nf_defrag_ipv4.ko          nf_nat_ipv4.ko             nf_reject_ipv4.ko
ipt_REJECT.ko              iptable_filter.ko          nf_conntrack_ipv4.ko       nf_log_ipv4.ko             nf_nat_masquerade_ipv4.ko

Code

root@zgemmah7:~# ls /lib/modules/`uname -r`/kernel/net/netfilter/
nf_conntrack.ko   nf_nat.ko         xt_connbytes.ko   xt_connmark.ko    xt_state.ko
nf_log_common.ko  x_tables.ko       xt_connlimit.ko   xt_multiport.ko   xt_tcpudp.ko

But when I try to load iptables NAT through wireguard launching

Code

[#] iptables -A FORWARD -i wg0 -j ACCEPT; iptables -A FORWARD -o wg0 -j ACCEPT; iptables -t NAT -A POSTROUTING -o eth0 -j MASQUERADE

Perhaps iptables or your kernel needs to be upgraded.

Any helps it should be really appreciate!

OpenSpa installed iptables in some receivers, not all receivers could activate iptables

Test the last openspa in your receiver, maybe you have luck
