Hi I want to setup 2 domains on my network. Domain One I shall call LAN this is where my LAN machines and my internal Exchange will be and all user mailboxes. Domain two I shall call WAN This is where my Public IP address will be on my second NIC for my broadband connection and my Exchange and Proxy. How would I configure to get Exchange in WAN to relay messages to LAN and viceversa. Are there no relaying prohibition issues that will come up. Also how can I redirect my OWA on WAN to point to LAN and also smtp and pop connections from my mobile users. I know third party softwware like WINGATE can do web traffic redirection. What about with what I have?? Naboth
