Telnet and SSH configuration

[Sagar Hiremath]

I do understand that we can use ACLs to deny / permit telnet / ssh traffic by configuring extended ACLs with port numbers.

What i'm trying to know is when we configure transport input ssh on vty lines, it allows only ssh, but not telnet.

Take a scenarios where i have 3 routers connected by a switch. I would allow one router R3 to only telnet to R1 while other R3 to telnet and ssh to R1

Please let me know how to do this??

Hi,

Let's suppose R1 is 10.0.0.1 and R2,R3 are respectively 10.0.0.2 and 10.0.0.3

on R1:

ip access-list extended VTY_ACCESS

deny tcp host 10.0.0.3 host 10.0.0.1 eq ssh

permit ip any any

int f0/0

ip access-group VTY_ACCESS in

line vty 0 4

transport input telnet ssh
