The source address of 192.1.24.2 is what I don’t understand. For the task you mentioned below I understand the explanation but what about 192.1.24.4 on R4, How will R4 F0/1 authenticate to the virtual telnet address if not allowed in the ACL?
From: Brandon Carroll [mailto:[email protected]] Sent: 29 April 2010 06:52 AM To: Johan Bornman Cc: [email protected] Subject: Re: [OSL | CCIE_Security] Lab1 Task 1.9 The task states: R2 should be able to Telnet into 192.1.24.15 (R5‟s translated address). Configure R5 to allow R2 to telnet into port 3025. Configure the ACL as needed to allow communication. R2 is 192.1.24.2, The Virtual Telnet address is 192.1.24.9. If you don't telnet on port 23 to the virtual telnet address you cant authenticate. Once you do that, from R2, then you can telnet to the 3025 port on R5.
