X firewall proxy
The X firewall proxy (xfwp) is an application layer gateway proxy
that may be run on a network firewall host to forward X traffic
across the firewall. Used in conjunction with the X server Security
extension and authorization checking, xfwp constitutes a safe, simple,
and reliable mechanism both to hide the addresses of X servers located
on the Intranet and to enforce a server connection policy.
