Good Net Neighbor - Level One

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.

There is no additional fee for this service.


All MOREnet Internet connections are eligible for this service.
