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 net-trouble@illinois.edu.

Firewall Request Guidelines

  • Each network should be in one firewall group only.
  • Requests to move networks into firewall groups must be made by people listed as contacts for that network.
  • IPv4 and IPv6 ranges for a single network must be placed in the same firewall group.
     
  • Requests to move a network into the Fully Open firewall group must be approved by Security.  Requests should still be submitted to net-trouble@illinois.edu.  Networking will initiate the process to get approval from Security.
  • Placing and removing hosts from the firewall groups is a "normal business hours" service.  If you need this change made at a specific date and time, please indicate that when you submit the ticket.
