如何获取防火墙 IP 地址的详细信息

Question

Is there any way to check firewall IP address, port number, subnet mask using PowerShell command?

I tried search, however, got only Primary IP instead

Answer 1

You can only get back what you ask for. So, you need to know how to ask the target for it.

A firewall device is nothing but a regular computer, even if it is purpose built. So, if you can reach it, just use the PowerShell network, network adapters, connection and firewall cmdlets to get information about it. That is if the FW you are trying to reach supports it.

There are several examples for you to use in the PowerShell built-in help files. So, you should find all the examples you need here:

Get-Help -Name Get-NetIPConfiguration -Examples
Get-Help -Name Get-NetAdapter -Examples
Get-Help -Name Get-NetIPAddress -Examples
Get-Help -Name Get-NetIPInterface -Examples

That first one will give you virtually all you are asking for, except for ports. FW's can have a lot of ports open, so, you need to just do a port scan on it to see which ones are open. That is what the cmdlet below is for.

Get-Help -Name Test-NetConnection -Examples

Just pipe in a list of ports using a for loop.
