Q1: Write a (simple) program to simulate processing of a packet at a router interface with an ACL bound to that interface. Given an ACL (standard or extended) bound to a router interface, your program should accept as input a packet with a source IP address, destination IP address, source port number and destination port number, check the ACL permit and deny statements in sequence and determine if the packet gets discarded or forwarded.
In order to do this, your program should read two text files:
File no. 1 contains the ACL (for example):
access-list 1 deny 172.16.4.13 0.0.0.0
access-list 1 deny 172.16.5.0 0.0.0.255 etc.
interface EO
ip access-group 1 out
File no.2 contains a list of packets (just source and destination addresses)
172.16.4.13 172.16.3.2
172.16.5.2 172.16.3.4
etc.
Your output should be something like this:
172.16.4.13 172.16.3.2 denied
172.16.5.2 172.16.3.4 denied
etc.
You may assume a specific network configuration. (look at file).
