I have the following set up:
Sonicwall Pro230 Firewall ==> ISA/proxy server ==> exchange server
I only have one external ip address, and I want to set up mobile devices to be able to connect to Outlook and get calendar/contacts/email through a cellular data connection. Exchange is set up for OWA and OMA is currently turned on, but I cannot figure out how to configure a device to pass through the external ip address via (pop3/imap4/whatever) and get through the ISA proxy server to the exchange server. I've read a bunch of stuff about activesync, and desktop redirectors, but I would rather not have to leave pc's running to send the outlook data to the wireless devices. The devices I am trying to connect with are:
Treo 650 with Sprint service and a Cingular 8125. If more details are needed please ask.
