permit tcp any any eq telnet--------------I added this
ip access-list extended OUTBOUND
permit tcp any any reflect GOODGUYS
permit udp any any reflect GOODGUYS
permit icmp any any reflect GOODGUYS
line con 0
line aux 0
line vty 0 4
An important point to note about reflexive access-lists and CBAC is that
an outbound access-list does not affect traffic locally generated by the router.
This means that traffic the router originates (routing protocol traffic, telnet, ping,
etc) will not get evaluated.
There are two choices to deal with this problem. You can either explicitly permit this traffic to return (I am consider ting on this), or you can policy route all locally generated traffic to another local interface first. The first method is easier, and the second is potentially more secure.
Why wont adding this line be useful for a successful telnet ?
