exchange to the internet

[strayrog]

I currently have Mac server directly connected to the internet acting as my mail server. I also have an exchange server on the inside network. Both are up and running but he field people can not get access into the exchange server without first logging on to the vpn. I am hoping to connect my exchange server to the internet to give the field people the same access of shared calendaring, meeting requests and etc that exchange offers.

How can I hook up my exchange server to the outside internet and keep my network secure?

Forward port 80 (or 443 if you're using SSL) to your Exchange server from your VPN router.

That's what I've done and it works perfect.

By just forwarding port 80( or 443), that will give outside users full exchange access without connecting to the vpn first?
