Yes, the Junxion Box contains an advanced stateful firewall. Packet filtering in the Junxion Box is achieved using the netfilter/iptables hooks available in the Linux kernel as a standard part of all modern distributions. NAT, port forwading, port restriction, and MAC filtering are all examples of services provided by the Junxion Box firewall.
