Hi AndresC2
You are welcome. Thanks for confirming that fixed it.
I just ran modinfo on conntrack:
tc@E310:~/x$ modinfo /usr/local/lib/modules/4.19.10-tinycore64/kernel/net/netfilter/nf_conntrack.ko.gz
filename: /usr/local/lib/modules/4.19.10-tinycore64/kernel/net/netfilter/nf_conntrack.ko.gz
license: GPL
parm: nf_conntrack_helper:Enable automatic conntrack helper assignment (default 0)
parm: acct:Enable connection tracking flow accounting.
parm: tstamp:Enable connection tracking flow timestamping.
alias: nf_conntrack-10
alias: nf_conntrack-2
alias: ip_conntrack
depends: nf_defrag_ipv6,nf_defrag_ipv4
intree: Y
vermagic: 4.19.10-tinycore64 SMP mod_unload
tc@E310:~/x$
nf_defrag_ipv6 is provided by ipv6-KERNEL.tcz so it looks like ipv6-KERNEL.tcz should be added to netfilter-KERNEL.tcz.dep.
