Re: Subnet of my router

Hello,

a starndard ACL invoked as access-class in in line vty 0 5 configuration can do this

example:

access-list 22 permit 10.10.20.0 0.0.0..0.255

line vty 0 5

access-class 22 in

Hope to help

Doesn't that command disables telnet completely on the VTY lines 0 to 5?  Can a user speciy what telnet line to connec to??

He might be better off specifying what subnet a user can telnet from and apply it to the appropriate interface

No, it does not do that.

No, as it would not make sense.

Actually, that is exactly what the command "access-class", correctly suggested by Giuseppe (and that I have rated), does,
