I have an exchange 2007 activesync server set up on my internal network, with no Edge server. I have the push tech configured correctly, and users receive emails with no trouble externally. However, when they are on their local LAN using the mobile devices WiFi, they are unable to make a connection.
I understand this is due to Local Loopback not being enabled, or as Linksys call it, "Filter Internet NAT Redirection".
I know it is possible with DNS to set this up, but we have an external DNS server for our web domain. Which makes it a bit of a clunky solution.
Is it a case of setting up a static route? or maybe a bit more difficult?
