Writing ACLs

Aisak6888

Level 1

I am in a college course and I am completely at a loss on this assignment. I've researched this all day and I have just gotten more confused. Here is the Assignment:

In this project, you're given sets of criteria, and then you write standard or extended ACLSs to control specific traffic.

Assume a Class B network masking of 255.255.0.0, unless otherwise specified

1. Write an ACL to achieve the following:
a. Allow Telnet connections to the 192.168.1.0 network from host 10.3.4.7
b. Allow established connections from network 172.16.0.0 to anywhere
c. Permit all other access

2. Write an ACL to achieve the following:
a. Prevent Telnet access from network 192.168.1.0 to network 172.16.0.0
b. Prevent reserved address from accessing any network
c. Deny spoofing from the default route and broadcast address
d. Permit all other access

3. Write and ACL to achieve the following:
a. Deny ICMP traffic
b. Permit to FTPServer01
c. Permit to the e-mail server XYZCorpMail01
d. Permit any host to access the Web Server named XYZWeb01
e. Allow access to all unrestricted ports 1024 or higher
f. Deny all other access


Help is appreciated...I am at a complete loss right now

If you go to Safari, you can get a free trial for online books. Take a look at Cisco IOS Access Lists. It is a fantastic book on ACL's and explains them very well.
