I have been working with support on getting WMI polling to work through a firewall (Ticket#: 56860). I have followed the suggestion on the MSDN for a specific port (http://msdn.microsoft.com/en-us/library/bb219447(VS.85).aspx) but now I am not even able to poll the WMI from a host that is wide open through the firewall that I was before making this change.
I would like to restrict this down to a port or set of ports if possible. I have several servers behind various sorts of firewalls and if I allow all traffic from the poller it works (without the suggestion above) but it does not if it is only locked down to a given port.
Has anyone done any work with getting the WMI to work through a firewall?
Thank you
I believe you have to enable the Windows Firewall: Allow remote administration exception. Open a command prompt on the firewalled computer and type:
netsh firewall set service RemoteAdmin enable
This is from:http://msdn.microsoft.com/en-us/library/aa389286(VS.85).aspx
I actually don't have the windows firewall enabled at all. The firewall I was refering to is a PIX in a couple cases and just juniper ip/port filters in another case.
