Does anyone know of any existing work on how to handle the
Kerberos protocol across firewalls?   I'm referring to dual-ported
bastion hosts running application gateways, as opposed to filtering
routers (which aren't a problem).  E.g., the client is behind a
firewall, and/or the server is behind a firewall, and/or the KDC is
outside the firewall.

A lot of issues arise in these scenarios, including failure of the
connection/ticket client-address check (on the server-side) due to the
dual-ported nature of the firewall, and needing a Kerberos protocol
gateway if the KDC is not inside the firewall.
