Kerberos through gateway

[Casey T. Deccio]

I have a network on which machines do not have direct access outside.
Instead they are required to go through a particular machine which acts
as a gateway/proxy for various services.  I'd like to have the inside
machines request kerberos tickets from this gateway, which will send the
requests as a proxy.  The only reference to something like this that
I've been able to find is IAKERB [1], which is apparently Internet-draft
status, and for which I haven't seen any implementations.

Any ideas?

Regards,
Casey
