Networking, Firewall, Service Participation

For IT Pros: This page contains information about how campus IT pros can add groups of computers under their control to the different campus firewall groups.

All campus networks with assigned IP space participate in the Firewall Service Plan. If no other group has been specified by your unit, your network is in the Fully Closed group.  If you have private (RFC 1918) IP space using NAT, that is also in the Fully Closed group. To request that a network be moved to a different group, please submit a ticket to the Help Desk by emailing
