Enable SSH on Debian-Lenny Server
I am trying to allow a consultant access to my Debian Server and am a Linux newbie. I am unable to access the server from outside the network using SSH. I have two firewalls between the server and the outside. I have created an inbound service on the main firewall directed to the ip of the second firewall. Then on the second firewall I have allowed the ssh access to the internal ip of the server. Do I need to do something with NAT at the main firewall or do I need to configure the Linux Server to allow access from outside IP's?

I figured it out SSH was being blocked from the DSL modem. I will award some points for the help.
Thanks

Yup in fact it always helps to check
- if it is locally accessible? If it is the daemon is working
- is accessible form the same lan ? If it is it means that both the firewall is allowing SSH and network setup is OK
- IS it accesible from outside? If not it might indicate that
- Reverser not is not set-up
- Firewall is preventing it
- Default gateway definition on SSHD Server might be wrong (since we know that it is accessible inside)

# ssh localhost
I tried the command:
/etc/init.d/ssh restart
and recieved this message:
Restarting OpenBSD Secure Shell server: sshd.
Does this shed any light? Thanks for your attention with this.
