We can only connect to ActiveSync on our exchange server from the outside world (using our external IP address). This is true for iPhone, Android, and OWA (outlook web access).
Once we connect one of these devices to our INTERNAL wifi network, ActiveSync can no longer work because the device cannot see the external IP once it's on our internal network. We have to reference the internal IP to gain access (highly undesirable as you can imagine).
I know the issue, but I don't know what this is called or what needs to be done on the router to "forward" the requests internally. Is this called "internal IP remapping" or something? I can't find any settings on our RV042 cisco gateway to configure to "map" the external IP back to the internal IP of the exchange server.
Any assitance is helpful :)
Thanks, this worked. Since our Server 2003 is our DNS server, I was able to go into DNS management and add a new zone and A RECORD for webmail.OURDOMAIN.com which pointed to itself (the 2003 server IP). Immediately the internal computers could access the server using the alias. – degenerate – 2012-08-24T18:45:18.597
