Answering my own question for future inquirers - After successfully testing an lxc container as a NAT gateway, I resumed testing on openvz. I remembered there was some sort of setting to enable iptables in a container, and eventually found it:
# prlctl set MyCT --netfilter full Of course, fighting with firewalld is a whole different set of problems, but with firewalld off, it works perfectly. I'll either find the magic tweak that makes firewalld allow the forwarding, or I'll live without firewalld for now.
