I am getting ready to setup Exchange 2000 for my network. I am behind a CISCO 678 router and that router is using NAT/DHCP to assign IP addresses to hosts for the intranet. My question is this, Is there a way to get my Exchange server “public” without having to get my ISP to host an MX record so that people can send email directly to my server and not to my ISP. Any help greatly appreciated!!!!
