Can’t start firewalld

by

I restarted my VPS and now firewalld isn’t running and I can’t seem to start it.

# systemctl is-enabled firewalld
enabled

# systemctl is-active firewalld
active

# firewall-cmd --state
not running

# firewall-cmd --reload
Error: '/sbin/ip6tables -t raw -I PREROUTING 2 -m rpfilter --invert -j DROP' failed: ip6tables: No chain/target/match by that name.

I’m at a loss for what to do next. I’m not sure where this iptables rule is defined. I know if I try to type the command by itself:

# /sbin/ip6tables -t raw -I PREROUTING 2 -m rpfilter --invert -j DROP
ip6tables: No chain/target/match by that name.

This is CentOS7
