We have configured the ssh configuration in our ASA firewall, We are able to access the asa firewall through ssh from intranet using outside interface public ip but not able to access the same through public network, even i tried (SSH 0.0.0.0 0.0.0.0 outside)also but no luck.
anyone please help on this.
so, I see, that you are getting the IP-address to outside interface from
ip address pppoe
Could you, please, verify, that the PPPoE ISP doesn't block tcp port 22? It is very easy to do. I need to use packet-capture on ASA.
capture TEST-SSH interface outside match ip host X.X.X.X any
where X.X.X.X - the IP-address, from where you are trying to open SSH-Session
then try show capture TEST-SSH to view capture-buffer.
