External SSH access to Cisco 1800 Router

[jpeterson6]

Hello,

I'm trying to figure out how to access a  Cisco 1800 router via SSH from a different network/ISP. Pretty much all  documentation I find on the subject refers to accessing routers via SSH  from internal networks.

Long story short I want an easy but safe way to remotely manage a router through an ISP with no VPN setup. The router is configured with PPPoE. Do I need to configure anything on the Dialer interface?

Can anyone point me in the right direction?

Thanks,

Jeff

Hi Jeff,

If you know the public ip from where you will be accessing then you can apply the acl with particular ip and access class applied on line vty,Following is the example to apply access class to apply in vty

The following example defines an access list that permits only hosts on network 192.89.55.0 to connect to the virtual terminal ports on the router:
access-list 12 permit 192.89.55.0  0.0.0.255
line 1 5
access-class 12 in

Hope to Help !!
