CS does not have a network firewall in place, but JHU has a perimeter firewall in place between the Internet and JHU.

If you need a port open on the JHU Firewall, you need to request it from JHU.

Requesting JHU to Open a Firewall Port

Official Process

Please see JHU's NonCloud Public IP Addressing process document for instructions to request port openings through the JHU firewall.

You should start the above process at step number four, "CMDB Registration". (Steps one and two are already taken care of by us provisioning a CS IP address for you. Step three is taken care of as long as you have an IP address on the CS public grad network.)

All questions and follow-up regarding these instructions need to be addressed to JHU Networking or JHU Network Security (nsi@jhu.edu). The JHU Helpdesk at 410-516-HELP may be able to direct your questions to the correct team.

Alternative (Older) Method If Unable to Use Above Method (Link Not Working, Etc.)

All port opening/closing requests should be emailed by the requester to nsi@jhu.edu as JHU's Network Security team is responsible for the JHU perimeter firewall. You will have to provide:

  1. Your system's full hostname (including the domain part) and IP address and
  2. Specific reasons as to the need of each of your port openings and
  3. Allow JHU to run security scans on any equipment for which you request port openings.

All questions and follow-up regarding these instructions need to be addressed to nsi@jhu.edu
