Hi,

You could configure an access-list for blocking telnet traffic from
WAN and configure a rotary

access-list 112 deny   tcp any any eq telnet
access-list 112 permit ip any any


line vty 0 4
 password cisco
 login local
 rotary 99                          (to enable access from port 3099)


Regards,
