Provide a filter table and a connection table for a stateful firewall that is as restrictive as possible but accomplishes the following:

Allows all internal users to establish Telnet sessions with external hosts$]$ Allows external users to surf the company Web site at $222\mathrm{.}22\mathrm{.}0\mathrm{.}12.$ But otherwise blocks all inbound and outbound traffic.

The internal network is $\frac{222\mathrm{.}22}{16}.$ In your solution, suppose that the connection table is currently caching three connections, all from inside to outside. You will need to invent appropriate IP addresses and port numbers. $[25$ pt$]$
