Endpoint Protection Small Business Edition

I'm new to configuring a firewall through this program and need to know how I can open a few ports for a companies software. I have mainly just went in and made a new firewall rule allow access to those ports, but when I scan the ports they come up closed.

Are you doing this on a managed or unmanaged client? If managed, there is a good article here http://www.symantec.com/business/support/index?page=content&id=HOWTO80979&actp=search&viewlocale=en_US&searchid=1425077090033

Unmanaged

Are you creating rules to allow access from specific hosts? Or just opening up ports to/from all hosts?

Thank you for posting in Symantec community.

You want to know how to configure firewall rules on an unmanaged Symantec Endpoint Protection (SEP) clients with Network Threat Protection installed? Refer this article:

Firewall Policies on Unmanaged Clients

Wanting to open up ports to/from all hosts
 

Should be a quick rule to setup:

Firewall policies on unmanaged Endpoint Protection clients

 

So your saying that all I need to do is allow the selected ports?

Yes, pretty much.
