Looks like a problem with your iptables installation which can't find libxt_DNAT.so? In v1.8.9 this should be a symlink to libxt_NAT.so. If you run 'iptables -j DNAT --help' and it doesn't say "DNAT target options:" at the end then it very much looks like a problem with your iptables installation and not the kernel. > try with kernel 6.1.11 6.1.12 6.1.13 Tested iptables-nft and iptables-legacy on 1.8.9 with kernel 6.1.14, no problems. There were no significant kernel changes in this area that I know of in 6.1 either.
