Do you have access to the firewall?
	If so add a rule to allow tcp/22 to the right sshserver.

If not, what ports are any ports already forwarded/allowed to the right
sshserver?

If not can you config the right sshserver to open a VPN tunnel to the
left sshserver (preferably openvpn since it is easiest to pass through
firewalls)?

Basically, somehow the tunnel needs to be allowed to connect to the
right sshserver.  This can be done by poking a hole in the firewall to
allow it directly (optimal) or by having a tunnel built back to the
other server if the firewall config is locked down and you can't change
it.  IIRC, you can also establish a reverse ssh tunnel from the right
ssh server back but I think the VPN connection is better since the
daemon will retry with any new traffic (should the tunnel go down for
some reason).

Hope this helps,
