Deployment Wizard
The template allows you to deploy an OPNsense Firewall VM using the opnsense-bootsrtap installation method. It creates an FreeBSD VM, does a silent install of OPNsense using a modified version of opnsense-bootstrap.sh with the settings provided.
OPNSense is based in FreeBSD what is the official OS image publisher in Azure. This template deploys a FreeBSD 13.1 VM and installs OPNSense using the opnsense-bootstrap installation method. For the first deployment in an Azure Subscription it's required to accept the legal terms of the Offer with PublisherId: 'thefreebsdfoundation', OfferId: 'freebsd-13_1'.
You can accept it using either Azure CLI or Azure PowerShell as follow:
az vm image terms accept --urn thefreebsdfoundation:freebsd-13_1:13_1-release:13.1.0 -o none
Get-AzMarketplaceTerms -Publisher 'thefreebsdfoundation' -Product 'freebsd-13_1' -Name '13_1-release' -OfferType 'latest' | Set-AzMarketplaceTerms -Accept
The login credentials are set during the installation process to:
- Username: root
- Password: opnsense (lowercase)
*** Please *** Change default password!!! (In case of using Active-Active scenario the password must be changed in both Firewalls and under High availability settings)
After deployment, you can go to https://PublicIP, then input the user and password, to configure the OPNsense firewall. In case of Active-Active the URL should be https://PublicIP:50443 for Primary server and https://PublicIP:50444 for Secondary server.
- Updated FreeBSD to 14.1.
- Fixed a bug to deploy in a existing VNet.
- Added Serial Console support.
- FRR plugin for OPNsense is now installed by default.
- OPNSense 24.1 as default version.
- Fixed deployment issues.
- Added support to OPNsense 23.7 (set as default version)
- Removed Single NIC scenario support (due to lack of usage for the scenario).
- Added a configurable option for WAAgent version and changed the default for the latest version.
- Miscellaneous fixes and improvements:
- Updated all Bicep API Versions.
- Fixed some lint warning due to Bicep recent updates.
- Added support to OPNsense 23.1
- Added support to select versions (22.7, 23.1)
- Updated FreeBSD to 13.1
- Updated OPNSense to 22.7
- Updated Azure Linux Agent to 2.8.0
- Updated Python symbolic link to 3.9
- Updated FreeBSD 13 and OPNSense 22.1
- Added support for Floating IPs in External Load Balance Rules to allow Port Forwarding without causing assymetric issues.
- Enabled session Sync between Firewalls.
- Add Virtual IP of the External Load Balancer to support Floating Rules.
- Add support for a Windows Management VM in a management network.
- Create a new simplified deployment wizard.
- Bicep template refactory to support the new UI deployment wizard.
- Added Active-Active deployment option (using Azure Internal and External Loadbalancer and OPNsense HA settings).
- Templates are now auto-generated under the folder ARM from a Bicep template using Github Actions.
This OPNsense solution is installed in FreeBSD 12.0 (Azure Image). Here is what you will see when you deploy this Template:
There are 2 different deployment scenarios:
-
Active-Active:
- VNET with Two Subnets and OPNsense VM with two NICs.
- VNET Address space is: 10.0.0.0/16 (suggested Address space, you may change that).
- External NIC named Untrusted Linked to Untrusted-Subnet (10.0.0.0/24).
- Internal NIC named Trusted Linked to Trusted-Subnet (10.0.1.0/24).
- It creates a NSG named OPN-NSG which allows incoming SSH and HTTPS. Same NSG is associated to both Subnets.
- Active-Active a Internal and External loadbalancer will be created.
- Two OPNsense firewalls will be created.
- OPNsense will be configured to allow loadbalancer probe connection.
- OPNsense HA settings will be configured to sync rules changed between both Firewalls.
- Option to deploy Windows management VM. (This option requires a management subnet to be created)
-
TwoNics:
- VNET with Two Subnets and OPNsense VM with two NICs.
- VNET Address space is: 10.0.0.0/16 (suggested Address space, you may change that).
- External NIC named Untrusted Linked to Untrusted-Subnet (10.0.0.0/24).
- Internal NIC named Trusted Linked to Trusted-Subnet (10.0.1.0/24).
- It creates a NSG named OPN-NSG which allows incoming SSH and HTTPS. Same NSG is associated to both Subnets.
- Option to deploy Windows management VM. (This option requires a management subnet to be created)

Here are few considerations to deploy this solution correctly:
- When you deploy this template, it will leave only TCP 22 listening to Internet while OPNsense gets installed.
- To monitor the installation process during the template deployment you can just probe the port 22 on OPNsense VM public IP (psping or tcping).
- When port is down which means OPNsense is installed and VM will get restarted automatically. At this point you will have only TCP 443.
Note: It takes about 10 min to complete the whole process when VM is created and a new VM CustomScript is started to install OPNsense.
- First access can be done using HTTPS://PublicIP. Please ignore SSL/TLS errors and proceed. In case of Active-Active the URL should be https://PublicIP:50443 for Primary server and https://PublicIP:50444 for Secondary server.
- Your first login is going to be username "root" and password "opnsense" (PLEASE change your password right the way).
- To access SSH you can either deploy a Jumpbox VM on Trusted Subnet or create a Firewall Rule to allow SSH to Internet.
- To send traffic to the OPNsense you need to create UDR 0.0.0.0 and set IP of trusted NIC IP (10.0.1.4) as next hop. Associate that NVA to Trusted-Subnet.
- Note: It is necessary to create appropriate Firewall rules inside OPNsense to desired traffic to work properly.
