Hy group!

        Does anybody know, why when you use dynamic acl you can't do a
telnet to the equipment? And if does it exist anyway to correct this?

        I have the next configuration:

        interface ethernet 0/0
                ip access-group 130 in
        !
        access-list 130 dynamic firewall timeout 2 permit tcp host
192.138.1.1 host 192.138.3.3 eq telnet
        access-list 130 deny tcp any host 192.138.3.3 eq telnet
        access-list 130 permit ip any any
        !
        line vty 0 4
                password cisco
                login
                autocommand access-enable host timeout 1
        
        And whe you try to telnet though any interface you always receive
the next message after the authentication:

        Password:
        List#130-firewall already contains this IP address pair
        [Connection to 192.138.2.2 closed by foreign host]

        Thank you very much!!!
