Changing Proxy Settings in Internet Explorer

Some Internet Service Providers (ISPs) in the Guam and CNMI get their Internet bandwidth via upstream Asian providers. Because of this IP addresses assigned to Guam and CNMI ISPs are primarily IPs assigned to Asia. In some cases the Centers for Medicare & Medicaid Services (CMS) as well as various other US Federal agencies only allow access to their websites and services from US affiliated IP addresses to reduce the risk of unauthorized access to their systems. The CMS EHR Incentive Program is one of those websites which blocks unauthorized IP addresses.

Unfortunately because of this Eligible Providers and Eligible Hospitals in Guam and CNMI may be unable to access the CMS websites. To fix this problem you can use a proxy server setup by your ISP which will route traffic to a US based Internet Service Provider. Below are procedures for enabling the proxy settings in your Internet Explorer.
