I have an internal SBS 2011 domain configured with Exchange 2010. I am setting up a wireless access point that is on the same subnet as my internal network mostly for our iPhone's. Everything seems to work great and I even have internet access when connected to the access point. The issue I am having is sending email from my Exchange account on the iPhone. On my iPhone I have my domain exchange account configured and pointing to my public exchange server address, mail.domain.com, for example. But when trying to send email on this access point it does not work. My guess would be that since this access point is internal and the Exchange email account on my phone is pointing to the public address it simply does not know how to route email to my internal exchange server.
How would I allow any wireless device on this access point to send exchange email to my internal mail server? I'm not sure if this could be a DNS issue, or if the access point simply doesn't know how to route this properly and needs to somehow be pointed to my internal domain exchange server.
Any information is appreciated.
