Answer to Question #91799 in Computer Networks for Hung

Question

Provide a filter table and a connection table for a stateful firewall that is as restrictive as possible but accomplishes the following:
a. Allows all internal users to establish SSH sessions with external hosts
b. Allows the external users to surf the company web site at 222.22.0.12
c. Allows all DNS traffic
d. But otherwise blocks all inbound and outbound traffic
The internal network is 222.22.0.0/16. In your solution, assume that the connection table is currently caching 3 connections, all from inside to outside. You’ll need to invent appropriate IP addresses and port numbers.
