Cisco 2500 Configuration to Access Remotly

Here is a really cool program I found called SSL-Explorer which allows me to access all of by resources at home using Java and encrypting it in SSL sshtools.com . If you only want to access the CLI of you router I would strongly suggest using SSH to access your router as telnet is sent in clear text. Of course use a strong username and password.

aaa new-model
username remoteadmin password 0 C!sc0Pa$$w*d

ip domain-name cisco.com <-- DNS domain

cry key generate rsa <-- Generates an SSH key to be used with SSH.
ip ssh time-out 60
ip ssh authentication-retries 2

line vty 0 4
transport input telnet <-- Prevent non-SSH Telnets

Verify with a show command
