I have a hosted server that’s located at a data center that I pay for monthly (www.liquidweb.com). The server is running windows server 2012 standard. The server is used to host a SQL database and a FTP server (no website). The server has an external IP address assigned to it from the data center. I access the resources of the machine through that IP address (SQL and FTP). I have recently decided that I need an additional machine for other purposes so I am attempting to setup a VM using hyper-v. The guest OS is also Win Server 2012 standard. Installation went perfect, but the only issue I am having is getting the correct network settings. I do not need this VM to have an externally facing IP address (an internal 10.x.x.x address is fine as long as the VM has internet access and the ability to talk to the host machine through standard windows networking) I followed the instructions in step 5 in the link below to setup RRAS with NAT: http://community.spiceworks.com/how_to/show/1161-hosted-windows-servers-hyper-v-and-creating-a-secure-network
Everything works perfectly however I can no longer access the resources of the host computer through its external IP address. I can still remote to it via Teamviewer (and I’m sure RDP although I have not tested) and both machines host and guest have complete access to the internet, but now when I try to access SQL or FTP via the external IP address I can no longer reach it. I hope it’s just some silly setting I forgot to check but it’s got me knocking my head against the wall. Also, I should mention that networking is not my strong suit. Thanks in advance for the help.
