I basically want to block all traffic from China/Russia and a few other places from ever reaching any container on this particular server.

It seems an abundant number of rules to place at each container.

Is it possible to filter from IPs from the host node before it's passed to the container?

Sure, just use netfilter/iptables on the HN. I've written a script to do all the filtering on the HN in order to protect the VEs

Thank you sunoano. This script is a little over my head can you point me to some instructions on how to deploy?

there is a link in the script that points to my website where you find plenty of information on how to deploy (top section, in the comments)
