Hello Experts. I am interested in setting up a home lab env using vmware workstation 11.0, for microsoft exchange. I would like to set it up so that i can have mailflow going to and from the internet. Im not quite sure how i can set up the network to do this. My residential isp blocks smtp. Is there another way of going about this? Do i need to register a domain and have public dns with someone like godaddy? My current env is 2 domain controllers, 1 exchange 2010 server hosting the mailbox and hub transport role, 2 servers for CAS, and 1 edge server. So i need external connection on the edge. My end goal is to migrate from exchange 2010 to 2013 then to o365 for practice. Please assist. Thanks in advance.
