Hi Marc,

Your answer did not meet one of the requirements, which is:
- Use the minimum amount of access-list entries to accomplish this

Their solution uses 2 entries which is the minimum. Yours uses 3
entries. Note that the question is to use the minimum number of ACL
entries, and not minimum number of commands!

However, their solution is not all correct either! I would give both
Brian's 0 points for this task. The task states

"Work hours are from 9 AM to 5 PM Monday through Friday"

Why they use this statement???????

 periodic weekdays 17:01 to 23:59

Do they mean that everyone should work extra minute from 17:00:00 -
17:00:59 . Who will pay for the OT? Is Internetwork Experts willing to
take the bills?

Heheh.

Subject: Time Range ACL question

Hi guys,

Question (IE lab 9, 8.2 for those interesed):
- Configure R5 to block excessive surfing the internet traffic during
working hours so that they can only go to your internal web server at
148.26.3.100.
- After hours these users should be allowed full access
- Work hours are from 9 AM to 5 PM Monday through Friday
- Use the minimum amount of access-list entries to accomplish this

Their answer:
ip access-list extended DENY_INTERNET_SURFING
 permit ip any any time-range NON_WORK_HOURS
 permit tcp any host 148.26.3.100 eq www !

time-range NON_WORK_HOURS
 periodic weekends 0:00 to 23:59
 periodic weekdays 0:00 to 8:59
 periodic weekdays 17:01 to 23:59
!
interface fa0/1
  ip access-group DENY_INTERNET_SURFING in

My answer:
time-range WWW
 periodic weekdays 09:00 to 16:59
!
access-list 182 permit tcp any host 148.26.3.100 eq www time-range WWW
access-list 182 deny tcp any any eq www time-range WWW
access-list 182 permit ip any any time-range WWW !

int f0/1
 ip access-group 182 in

Is my answer ok as well?
Which answer is better?

Thanks
Marc
