How to allow telnet to ASA 5510

With ASA firewalls you need to specify what hosts are allowed to telnet/ssh into your system.
Don't know about SDM off the top of my head but in command line you need to add a line like:
telnet x.x.x.x y.y.y.y inside/outside where x is the IP and y is the subnet mask

give command

telnet 0 0 inside or
you can also specify single ip address.

Just a side note, telnet 0 0 inside will allow telnet from any device in your inside network, depending on your environment that may not be desirable.

Any update on this?

it's not working... is this done on the router?

It is done on the ASA

:( no luck... something is not right... i can ping to the router, but can't telnet to it

I finally found a post (http://www.experts-exchange.com/Networking/Misc/Q_22135267.html) and it looks like you can't telnet to other devices from ASA 5510
