Earlier this month, the Computer Protection Program implemented additional perimeter protection for DHCP hosts, making web servers that are connected to DHCP no longer accessible to the Internet. If you want to run a web server that must be accessed by people outside of LBNL (via the Internet), you must acquire and configure a static IP address.  To obtain a static IP address, please fill out this form.

Last December, an exception was made for Internet traffic destined to http (port 80) DHCP hosts, but the exception for http was removed earlier this month. Connections initiated to port 80 from outside of LBNL are now being blocked. Now http servers are protected from hostile attacks from the Internet, and they can still offer http services inside LBNL.
