Ran into an issue while upgrading a CorePure64 server to 10.x. Verified on a clean install in a VM.
While attempting to implement firewall, I received an error:
modprobe: can't load module nf_conntrack (kernel.tclocal/net/netfilter/nf_conntrack.ko.gz): unknown symbol in module, or unknown parameter
modprobe: can't load module nf_conntrack (kernel.tclocal/net/netfilter/nf_conntrack.ko.gz): unknown symbol in module, or unknown parameter
iptables v1.8.2 (legacy): can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
iptables v1.8.2 (legacy): Couldn't load match `state' No such file or directory
