You must know the public IP

You must know the public IP address, for example :

ssh 94.125.239.0 255.255.255.0 OUTSIDE

Hi, 

Hi, 

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.

Hi Boris,Apparently the issue

Hi Boris,

Apparently the issue was from ISP side.

Not really sure of what they did but now it's working fine.

 

Thanks for your help!
