-----BEGIN PGP SIGNED MESSAGE----- nuqneH, Hmm and how does classified side make requests? Or it does not? So what protocols can it use? Should be not so hard to implement, although.. Thanks for the information; the original message was too unclear about that.. Rick Murphy <rmurphy () mitretek org> said :

It's intended to be put between classified and unclassified networks so that information can flow up toward the classified network but nothing can leak back down. Vision Abell have built an x-windows proxy capability using this box. Writing proxies is difficult because you can't get any feeback (acknowledgements, for example) from the classified side back to the unclassified side because you have a write-only link. Your proxy has to mimic the behavior of the classified side and can't tell if the classified side is even listening. -Rick
