Configure Site to Site VPN to Microsoft Azure Using RRAS

In our previous post, we have talked on building RRAS to connecting two subnet and network address translation. If you’re interested, feel free to check out here.

Next, we are going to embark a journey to Hybrid Cloud by connecting to Microsoft Azure by using RRAS.

[ Scenario]

Site2Site

Continue from previous post setup. We are changing it to include demand-dial.

[ Before – on Azure]

Create Virtual Network and create dynamic VPN Gateway. Take note and Gateway IP Address and Pre-Shared Key

s2s13

8. Modify the demand dial interface. Go to security tab and set to use pre-shared key

S2S14

[ Verification]

  • Try establish connection from RRAS
  • Connect on Azure Portal

s2s15

s2s16

Yeah! Both reported connected

To make sure that both side can access, perform ping test and tracert.

[ Test result]

From Azure VM to on-prem DC VM

From on-prem DC VM to Azure VM

Easy right!  That’s concluded our configuration to establish site to site vpn to Microsoft Azure by using RRAS.
