To go on a bit, would the "deny ip any any" in the Untrusted ACL on R2 not
cause users on the 150.50.17.0/24 not to be able to use the services
configured in question 10 - even if the time based entries are in effect?

Is this an example of things breaking in the during the lab as is implied by
the remark in the ACL?

The established line probably would have met the technical requiremeents...
We may have to look at the wording on there, because (IMHO) that leaves
things a little too lame!  :)  But hey, it's all about interesting changes.

As for the client ports, you likely could have specified gt 1023 there if
you wanted to, but the any would have worked as well.

Subject: [OSL | CCIE_RS] Lab9 IPExpert v9.0

Hi,

Just joined and currently working on lab 9 of the IPExpert Workbook. When I
look at the latest downloaded final configuration for question 2 (R4's
lambeau ACL), it specifically lists a line matching return traffic for web
servers followed by a line matching return traffic from FTP servers:

 permit tcp 10.1.1.0 0.0.0.255 eq www any  remark that line covers the
replies from web servers on the inside  permit tcp 10.1.1.0 0.0.0.255 any
established  remark that line is necessary for the FTP server responses
since ports vary

Would the answer not also be possible to be the following:

1. Just the established line

or

2. add gt 1024 to the FTP entry (not a stated requirement, though, I think)

Further, the answers seem to take server ports into account, but not client
ports, when specific entries are asked and to allow remaining traffic, if
only certain flows are explicitly stated to be blocked.
Is this normal lab practice, so to speak, or is it typically something to
ask the proctor?

Kind regards,

Kim Blom
