Extended Access List Problem #3 Deny/Permit Specific Addresses
Write a named extended access list called “Lab_166” to permit Jan’s computer at 218.35.50.10 to receive packets from Rachael’s
computer at 172.59.2.18; but not Rebecca’s computer at 172.59.2.15. Deny all other packets. Keep in mind that there may be
multiple ways many of the individual statements in an ACL can be written.
Place the access list at:
Router Name: ___________________________
Router B
Interface: _______________________________
FA1
Access-list Name: ____________________________
Lab_166
