I' have moved a hyper-v image of SBS 2008, from a local server, to a hyper-v server located in a datacenter. We have changed the ip address of the SBS to a public ip. However, in exchange, the transport still wants to connect to the local private ip.
The connection wizard doesn't support public, so we changed it manually. This is the log.
