Persisting arptables on Ubuntu 18

I am using Ubuntu 18 with UFW as the basic firewall.

I need to restrict some ARP traffic from the box, and I can that by using the following arptables command:

sudo arptables -I OUTPUT --source-mac source-mac-here --destination-mac destination-mac-here -j DROP

However, when I reboot the machine the arptables entries are lost.

How can I persist the arptable entries across a reboot?I need this to work with the existing UFW config.

Thanks
