Firewalld/IPSET/Nftable

Vicibox 10 Dynamic Portal use three major components

1. IPSET

2. nftables

3. Firewalld

ipset is a companion application for the iptables Linux firewall. It allows you to setup rules to quickly and easily block a set of IP addresses, among other things.

nftables is a Linux packet classification framework that replaces the Netfilter infrastructure behind iptables, ip6tables, arptables, and ebtables ,

firewalld is a zone-based firewall. Zone-based firewalls are network security systems that monitor traffic and take actions based on a set of defined rules applied against incoming/outgoing packets.

it is better to have knowledge in these components ,which helps in troubleshooting and understand how vicibox dynamic portal works, Check out my youtube video on Vicibox 10 firewall Video tutorial

STEP 1: Bug fix the VB-firewall code.
