Assuming the corporate network & security will permit.
I assume that there is some kind of firewall? And that it blocks port
22? Are they using a mandatory proxy?
I may be able to help you, if you give me more details. Are they using
ISA or Squid?

Kind regards,

If TCP port 22 (or whichever port the SSH is running on) is blocked
you can definitely not SSH into the box directly. What can be helpful
is a VPN with the server (hub) outside of the firewalled network. That
not only provides extra security but also allows one to access hosts
whose existence is not even advertised in any perceptible manner out
on the Internet.

I don't know if this has already been asked on this list, but why did I
get two copies of this email?
