Hello Guys ,
I'm studying Firewall and I performing a NAT Lab to improve my skills. The ideia is be able to access ssh from "Remote_Router" to "Firewall", ISP will perform a static nat from 200.0.0.6 to 172.16.0.2 Outside on "Firewall".
I can ping from Remote_Router to Firewall, but I can't access SSH, I don't understand what is wrong.
On the asdm I can see the error, it is in ASDM_ERROR.
Follow ISP's config :
