Пакет xfwp: Информация

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.  Xfwp  cannot  pro-
tect  against mischief originating on the Intranet; however, when prop-
erly configured it can guarantee that only trusted clients  originating
on authorized external Internet hosts will be allowed inbound access to
local X servers.
