With the introduction of Augmented rules for Network Security Groups (NSGs) in Azure, you can define larger, more complex network security policies with fewer rules. Multiple ports, multiple explicit IP addresses, service tags, and application security groups can all be combined into a single, easily understood security rule.
Unfortunately, Augmented rules is not available in Azure Stack as of writing this article. Network security groups (NSGs) do not work in Azure Stack in the same way as global Azure. In Azure, you can set multiple IPs and Ports on one NSG rule (using the Portal, PowerShell, and Resource Manager templates).
In Azure Stack however, you cannot set multiple IPs and Ports on one NSG rule via the portal.
To check the difference between Azure and Azure Stack networking, I highly recommend to keep checking the following Cheat Sheet document.
Set Multiple IPs on one NSG Rule in Azure Stack
Now what if you have a little less than a hundred of IPs to add as whitelists, and a large number of protocols to open on Azure Stack, you can hardly do it by hand on each NSG rule.
The good news is, starting with Azure Stack Update 1903, you can set multiple IPs and Ports on one NSG rule using either Resource Manager template, PowerShell, or Azure CLI.
What about the Portal??? Well this is ‘technically’ possible to do it via the Azure Stack portal due to a bug.
To set multiple IPs on one NSG Rule in the Azure Stack portal, take the following easy steps:
- Add first an NSG rule (Inbound or Outbound) with multiple IP addresses and single port, wait for it to throw an error ! as shown in the following screenshot, and then switch to Basic. By default, when you add an NSG rule, the configuration will be in Advanced mode.
- Once you are in Basic mode, you can click Add now.
- One the rule is added, you can verify the multiple IP addresses are set as desired :)
Unfortunately, you cannot add multiple ports range in the Azure Stack portal. This workaround applies only to Source and Destination IP address range. If you want to set multiple ports, then you need Resource Manager template, PowerShell, or Azure CLI.
Please note that this is not officially supported by Microsoft. It’s a workaround and hopefully Microsoft will address it in the near future.
Hope this helps!
