Never heard of a service like this.
If you want persistent iptables rules install
code {
font-family: Consolas,"courier new";
color: crimson;
background-color: rgba(0, 0, 0, 0.2);
padding: 2px;
font-size: 105%;
}
iptables-persistent package via apt.
iptables is active already once the kernel module is loaded which most likely is by default.
