Unfiltered IP address requests

ISC Networking will begin filtering inbound UDP and TCP traffic on ports 135, 137, 138, 139, & 445 on April 11th.

In preparation for filtering, ISC will reserve a block of unfiltered IP addresses to which a small number of servers unable to be secured in advance of the implementation can be moved. These unsecured IPs will be in place for a short period of time during which ISC will work with local system administrators to identify more permanent and secure methods of providing access to their servers.

To request a temporary unfiltered IP address, please send email immediately to millar@isc.upenn.edu  with the following information:

• Current IP address of the server(s) for which you require an unfiltered IP address
• Wallplate(s) of the impacted server(s)
• Number of users accessing the server(s)
• Reason(s) the server(s) warrants an unfiltered IP address
• Reason(s) why solutions such as Remote Desktop and Secure FTP are not viable

Unfiltered IP addresses will be granted subject to the approval of the School/Center IT Director, and will be limited to the most urgent needs. Please plan on 3-5 days to review and process a request. Additional information will be provided to groups or individuals requesting unfiltered IP addresses.
