Setting a firewall rule to block a single IP address

Nodegrid can act as a firewall to filter traffic.
It has six build in chains ( three for ipv4 and three for ipv6 ) - INPUT, OUTPUT and FORWARD
Default policy can be assigned for each chain. For each chain, rules can be added deleted and modified.
Custom chains can also be created and deleted when required.
