Best way to publish BI URL over internet for Public Users

Dear Expert,

We have requirement to publish BO Xi 4 BI URL over internet for Public Users.

Since my BO server is hosted in Application segment I can’t directly bind BI URL with  any reverse proxy

My Question –

1. 1) Is there any component which I can install in our Web Segment(kind of DMZ network) which can I  rout the traffic to BO Server which is hosted in our Internal network
2. 2) Can I use mod_jk reverse proxy or Oracle OHS server which can communicate with BI server
