I'm afraid I do not understand what you are asking.
Let me try to answer what I think you are asking.
I apologize if I'm wrong.
Let us say I want to ssh tunnel to a remote machine on a remote lan.
Let us say I want to tunnel ssh traffic through this ssh tunnel to
still a third machine on that remote lan.
Could I do something like the following in my ~/.ssh/config file:
Host remote
HostKeyAlias myAliasForRemote
HostName remote.com
LocalForward 2222 veryremotehost:22
Host veryremote
HostKeyAlias myAliasForVeryRemote
HostName localhost
port 2222
Now, could I do
ssh remote
and myAliasForRemote is what is associated with the host in my
~/.ssh/known_hosts file.
and as long as this connection is open, could I do
ssh veryremote
and myAliasForVeryRemote is what is associated with the host,
veryremotehost, in my ~/.ssh/known_hosts file.
I am not sure if the DNS name, "veryremotehost" needs to be resolved
locally or remotely. I think it is remotely, but you would need to
check. Normally, I would have used IP addresses because the hosts on
the company's internal lan did not have DNS entries.
The HostKeyAlias controls the name used for the host that is stored in
the ~/.ssh/known_hosts file.
Is this what you are asking?
