Hi
is it possible for me to ssh to a server through another server
reason is most of our servers are behind a load balancer and firewall
and they have private ip address so is it possible to ssh to a server using another server to relay the ssh request.
maybe use the server as a gateway

You can either SSH to the "gateway" machine and then from there SSH again to your destination machine, or, you can setup an SSH tunnel through your "gateway" machine if you don't want to manually perform two SSH commands.

Here's a link that will be helpful:

i dont think you understand what i want to do
there are 3 machines involved
a.Mine
b.server with public ip address and a private ip address
c.the server i want to ssh to but has a private ip address connected to a lan with server b.
and i dont want to ssh twice i want one ssh that will take me straight to c

u didn't mentioned that your machine is connected to which server "b" or "c". As i understand ur network - ur machine is "a", "b" is ur server and "c" is connected with "b". if u r connecting ur server "b" with ssh, redirect the ssh request to "c" with "dnat" of iptables.

Good idea ;-)

Hi
thanks for your reply but the wont the dnat forward all connections coming for my office ip address i am in my office LAN

I have a developer that lives 3 and a half hours from my server rack. He uses an SSH tunnel to do exactly what you are asking (actually, his is even more complex, but has the same basic parameters). His machine with his office's public IP address uses an SSH tunnel to a server in our DMZ (we specifically allow only that IP address access) with a public and private IP address (via firewall NAT) and then from that server hops in to an internal server that has no public IP address to do his development work.

Bottom line... an SSH tunnel is the proper way to accomplish what you're asking.

thanks but i have the idea of what to do but the problem is how do i do it
