already access my home server locally using its 192.168... address
Is it a classe C private Ipv4 address?
(actually through the /etc/hosts file using the server's name).
I've set up port forwarding on both my routers (I have an inner network
and an outer one, using the outer network for devices I don't really
control). I can access my Apache2 server on the inner network by
forwarding port 80 on the outer network to the WAN address of the inner
router and forwarding that to my server. Pointing my browser to the
external IP address of the outer router brings up the default page -
which I can change so I know it's the actual local page > However, when I try to ssh to the same address, it just times out.
I've compared the sshd.conf file on my local server to one on a remote
server and they are identical. The only uncommented lines are:
PasswordAuthentication no
ChallengeResponseAuthentication no
UsePAM yes
X11Forwarding yes
PrintMotd no
AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
Any ideas on what's going wrong?
- This looks like your port forwarding is not working...
- What are the logs saying?
- Is the SSH server allowing access from the outside?
Note that it is unclear to me how you can test outside access from the
inside.
