It started its beam operation in 2008, and since 2009 has been delivering beam to the T2K neutrino experiment and hadron experiments. Over the past decade, MR have become more sophisticated and more stable driving is required. Along with this, demands arose from users and experts of equipment such that acquiring detailed and real-time information on the apparatus from the office LAN. On the other hand, the accelerator control system is quarantined from the office LAN with firewall for security reasons. Therefore, despite being intentional or not, manipulating any equipment in the accelerator control LAN shall be prohibited from the office LAN. This article describes construction and prospects of such an one-way gateway system such that information is relayed via EPICS from accelerator control LAN to the office LAN while minimizing influence in the opposite direction.
