Extranet/Firewall implementation question

All,

We’re running EP6 SP11 on a single server scenario. We’ve implemented iviews that access backend CRM and BW systems. All connections are HTTP (verses SSL). I’ve been asked to make the Portal system available outside the firewall where the sales team can access sales functionality w/o VPN authentication. I’ve read about reverse proxy and SSL scenarios which make sense however I have a couple of questions.

It seems like the reverse proxy scenario would be a good choice. I understand how access to the portal would work however not sure what happens when the iviews which accesses backend systems are launched.

I would like to get others input.

Thanks,

Greg
