Problem with iptables-legacy NAT
I am able to get iptables NAT working on InceptionHosting Netherland node, but not on London and Phoenix.. All three nodes are installed with Debian 10 and have the same packages and configuration.
Is there any special configuration that I need?
On London and Phoenix:
root@phx:~# iptables-legacy -t nat -L
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.
root@phx:~# lsmod | grep iptable
iptable_security 4242 -2
iptable_nat 4242 -2
nf_nat_ipv4 4242 -2 iptable_nat
iptable_raw 4242 -2

make sure iptables is installed and check the knowledge base, run: touch /option.netfilter the wait 30 minutes and test again.

Please do not use the PM system here for Inception Hosting support issues.
maybe refer to this knowledgebase first (if it's Inception Hosting NAT)
Thanks! touch /option.netfilter did the trick.
