We have a small office of 6 people who want to run an Exchange 2010 Server on Windows 2012 server alongside another Windows 2012 server that is the domain controller and running active directory.
In normal environments we of course have and external Static IP that points towards a Comcast Business internet modem and then our routers behind that. In this case they refuse to deal with Comcast Cable because they hate them and they have residential Verizon FIOS TV and internet in the building already. Plus the internet speed they have of 150/65 now would be extremely expensive for them to do as Business with static.
Is there any safe way of running Exchange, Remote Web Workplace etc. without an external static public IP address? I know we could use the dynamic one that Verizon assigned initially and if it changes assume we would have to make the appropriate changes in the entire network each time it changed.
