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.There is no official package available for openSUSE Leap 15.4
