Hello All,
Not sure if this was the correct place to log this question, but this is my first time trying to set up my a VPN and I am running into a few snags. We are currently running two Windows Server 2008 R2's and here is an overview of what I am trying to accomplish. We bought a new MIS software application and were told upon purchase that the install should not go on a domain controller (Alpha). So we purchased a second server (Beta) to install the application on. We were informed after the fact that the client computers would only work if the computers were on the LAN. So going into further discussion we got to a point where the application can be ran offsite, but it had to be through Terminal/Remote Services. I do have Remote Desktop set-up, but it goes directly to our domain controller (Alpha) when remoting offsite. So for our offsite sales departments we need to create an access point that goes directly to our MIS server (Beta) so they can access the program and run it remotely. So far I have tried a couple different things. I tried to run Web Access and got it up and running, but can only be seen from our LAN. So if we can get that visible from outside the LAN that would work. The second thing I tried was installing the Remote Access Services Role on our Domain Controller and try to set up a VPN that the sales team could use and then just RDP into the MIS Server (Beta). However, this is where I am running into problems. I watched several videos and went through several guides to establish how best to install that role on (Alpha) and upon completion of installing the Remote Desktop Services Role and trying to test the VPN from an outside client I am having no luck. I was trying on a Windows 7 machine. Upon creating a new connection I was prompted for the user name and password and got through the verifiying user name and password portion than upon trying to connect through the "WAN Miniport (L2TP)" as the connection box stated it came to a fail screen with an error number of 800. So again I am new to this, but it seems like there is some sort of connection happening, but authentication isn't correct. The other variable in this is that there is a SonicWall TZ210 connected directly to the modem and then from the firewall to the VPN Server. So I would also not be shocked if there was settings within the firewall that are blocking the connection as when I looked up the ports that were open it didn't appear that any of the typical VPN ports were open (443, 500, 1701, 1723) and we have had a lot of problems fighting around that thing with other projects we have implemented. I'm not sure if this is enough for anyone to go off of, but any help at this point would be extremely appreciated.
Thanks,
Josh
