Yea my FreeNAS server has the IP address of 192.168.1.17. Not sure why I can't SSH into the server via the internet. I have shown what my setup looks like, but is it possible that my router doesn't support port forwarding? If I can see an open port with a port finder online, does that mean that my router is successful or not necessarily? Like someone else previously, I had the "no matching key exchange method found. Their offer: diffie-hellman-group1-sha1 " error, which I resolved by adding something to the SSH config file.You've configured the SSH service on your FreeNAS server to answer on port 8888; your router accepts inbound traffic on port 8888 and forwards it to port 8888 on IP address 192.168.1.17 -- this all looks good, provided 192.168.1.17 is the IP address of your FreeNAS server.
Is your FreeNAS server configured on IP address 192.168.1.17?
