Assume a web server can only receive TCP connections on port 80 (HTTP) and 22 (SSH), but not on any other ports. The web server can only establish connection to a database server hosted on private IP 192.168.100.100 on port 3000, but to no other machines inside or outside the network. Imagine this web server is running Linux, and we’re using iptables to define host-based firewall rules for it. Show the set of iptables commands to install necessary rules for this security policy.
