Hye Everyone,

I need to know, if these things can be done and (if yes) how they can be done through C# code :

1. to detect if any firewall is running on System.
2. to detect if any particular port (let say 9001) is blocked (outbound/inbound)
and if yes; how to know if its outgoing blocked or incoming blocked.
3. to detect if my IP Address is blocked by ISP or not.

Please, do reply..
~~its urgent~~.

FYI : (My application is on .NET Framework 4.0 (VS 2010))

thanks in advance..

Strange question! Contact to your Internet provider and ask them if your IP is blocked?

Thanks..
Can u please tell me how to use

INetFwMgr.IsPortAllowed

Shahin Khorshidnia 26-Mar-12 9:23am

INetFWMgr is an interface and you can use Activator.
for example:
INetFwMgr mgr = (INetFwMgr)Activator.CreateInstance(NetFwMgrType);

For more detail look at the updated answer.
