How to configure a router using ACL # 99 to allow remote telnet & ssh with password of "cisco" from subnet 172.16.1.128/25


A router (r1) has a trunk connection to switch (s1).

You have two subnets; users 172.16.1.0/25 and admins 172.16.1.128/25.


What would be the syntax commands to do this, as I do not know for sure if this is correct:


(config)# access-list 99 permit 172.16.1.128 0.0.0.127

(config)# access-list 99 deny any

(config)# line vty 0 4

(config-line)# access-class 1 in

(config-line)# end


thank you!

Keith,


For SSH, you would need a domain name configured on the router or switch, host name, and a ssl keys generated. For telnet, the config looks right, but your access-class would reference 99.


line vty 0 4

access-class 99 in


To generate your ssl keys:


crypto key generate rsa general mod 1024


HTH,

John
