Port Forwarding working for Apache but not SSH

sunzeal · 09-05-2013, 03:55 AM

Inside my internal network, i have Apache and SSH running ( in virtual machine ).

I have configured my router to port forward.

When i try for port 80 of Apache, it seems working fine from external network , but when i change it to 22 ( SSH ) and try to connect via SSH [ through router's public IP ] , it won't work.

Am i doing something wrong ?

Try enabling port forwarding on an different port (2222?) forwarding to your server on port 22 and see if that works. If it does then it's possible your router has remote management, and if it does then check to see if remote management by ssh is enabled on the external interface. If it's enabled then your router is getting the ssh traffic rather than passing it through.

You didn't mention your distro.

Have you opened respected port in firewall?

Can you connect to ssh locally (LAN) or are you facing problem in any case?

CentOS 6

I can connect via SSH locally and firewall is turned off.

try running sshd -d -d -d on the server and ssh -v -v -v on the client and see what debug messages pop up.

also, on fedora-live i had to make ssh a trusted service via system-config-firewall to get into my laptop (for some reason it was disabled by default).
