Good Net Neighbor Phase 1
In an effort to proactively reduce the number of security incidents caused by viruses and scanning, MOREnet offers a Good Net Neighbor Service to MOREnet customers. This is a low-risk, volunteer-based, no-cost service.
Level One of the Good Net Neighbor Service will implement access control lists to block Windows Networking ports (TCP/UDP ports 135, 137, 138, 139 and 445). These ports are sometimes used by worms and viruses to scan, discover and infect other computers through the Internet.
NOTE: Customers should be aware that this service is not a substitute for patching/updating machines or using anti-virus protection.
Blocking these ports may affect:
- Access to Microsoft Exchange servers over the Internet using MS Outlook (blocking these ports will not affect using MS Outlook over the local area network).
- File/print sharing over the Internet.
- Other programs or applications that are configured to use ports 135, 137, 138, 139 or 445 to communicate over the Internet.
See the following links for more information on ports used by Windows servers and services.
If you would like to participate in this service and you understand the potential issues that are involved in blocking the Microsoft Networking ports, please log on to your MyMOREnet account and select the Help Desk Ticket Management application. Click Submit a Ticket to Technical Support and create a new ticket for your organization. Set the ticket's category to Internet Security. A pop-up dialog box will appear indicating that all MyMOREnet users in your organization can view this data. Click OK. Enter text describing what you would like to have configured or paste the text below into the Describe the Problem or Request field.
I would like to sign up for Phase I of the GNN, the Microsoft Networking port blocking service. Please activate my block.
If you have more then one site/connection with MOREnet please use the Additional Information field to list the sites/connections you would like the GNN Phase I service applied to. You may state "all" if that is applicable for you instead of listing each site individually.
Once MOREnet Security receives your ticket request, we will begin to implement the changes on the core network. Once the configuration changes have been made, you will receive an e-mail saying the GNN service as been implemented.
If you have questions, contact MOREnet Security at firstname.lastname@example.org or (800) 509-6673.
