Setting up Routing and Remote Access Service on Windows Server 2012

Recently I came across a need to implement a simple VPN connection to my home network. I have a Windows Server 2012 box hosting my IIS, which also supports VPN connections over SSTP through the Routing and Remote Access Service (RRAS) without any need for 3rd party software on either server or client side.

To get started I followed the instructions on technet which outlined how to add the feature to the server and start the service. I already had port 443 forwarded through my router for IIS.

I was unable to get my external Windows client to connect right off the bat. I needed to configure a few extra settings. The server was unable to reach the local router DHCP services. I worked around this by adding a static IP pool for the server to pull from instead of the router:


I took this range of IPs out of what the router would hand out to clients to keep any IP address conflicts at bay.

I ensured that the user I was attempting to log in as had remote access permissions through the MMC console:


Windows 7 and above supports the VPN connection natively:


I found that after setting up the connection modifications were required to get the client using the correct protocol and credentials:


After these changes I was able to make a successful connection and tunnel my connection through my home network.


Since the SSTP protocol is basically an SSH connection, a valid trusted certificate is required to be installed on the server. the Windows VPN client does not support trusting non-verified certificates. If your connection address is, a SSL certificate with the same CN is required on the server. I already had a certificate installed on the server for use with IIS which RRAS picked it up automatically. I was surprised there was no issue with IIS and RRAS fighting for control of port 443 (used with both RRAS for SSTP and IIS for SSL connections)

Water Cooling the CM690 II Advanced Part 2

Realized today that moving the 140mm fans above the case divider causes the top lid to no longer attach to the case. The fans are simply too wide and block the lid from attaching. Have to move down to 120mm fans before reassembly can be finished completely.

I trimmed the water lines to get a cleaner appearance and reduce the overall length of my loop. I managed to remove about a foot of tubing.

After getting the water cooling installed I moved on to overclocking. Currently I am using the i5 3750K on the ASRock Z77 Extreme6 motherboard. The Ivy Bridge CPUs use thermal paste to connect the CPU die to heat spreader. I was having issues with one of the cores being 8-10 degrees hotter than the others. After delidding the CPU, cleaning up the thermal paste and applying some Arctic Silver 5, I got the temps to be grouped closer together. This was my first attempt delidding a processor. It ended up only taking 5 minutes, where other people took 45 – 60 minutes.

After delidding I was able to overclock to 4.5GHz on stock voltages with “Level 3” vdroop with temps around 60-70 degrees. Prime95 for 30 minutes was successful.

Got my 120mm fan today from Amazon, broken of course..

Organizing more of the cables for the fan controller and pumps. Out of sleeving at the moment 🙁

Coming together nicely 🙂
