Connecting to Dartmouth Resources from Off Campus

Many of Dartmouth's computing and information resources are available from off campus, although you need a connection to the Internet to access them. We recommend using a secure connection through a virtual private network (VPN) (authentication required).

One local ISP, Fairpoint Communications, has established a discounted Internet plan for Dartmouth employees. For details, see the Dartmouth Affinity Plan.

Connecting to the Internet from Off Campus

Most computers on campus are connected to the Internet via an Ethernet cable or a wireless connection. If you are at another location that has an Ethernet or wireless network, you may be able to configure your computer for that network. If you need information on configuring your computer for their network, contact their Computing Help Desk.

Using Another Internet Service Provider

While Computing Services does not provide support for home networks or for connections through other Internet Service Providers (ISP), there are several in the local area or around the world that can be used to access Dartmouth resources. These include:

Upper Valley Internet Service Providers

Recommendations and Cautions

Before you enter into an agreement with an ISP, we recommend you confirm:

An ISP's ability to support your computer model and operating system (whether it's Macintosh, Windows, or UNIX)

Their ability to help troubleshoot any connectivity problems you may have when trying to connect to their network

Also, be aware that some ISPs do "address translation" which will prevent Kerberos from working. If you are trying to access a Kerberos-authenticated system from a connection that goes through an ISP, try starting a VPN session, then accessing the system rather than trying to use a Kerberos ticket.

Connecting to the Internet While Traveling

Some departments contract with outside Internet Service Providers for calling cards that allow their staff members to dial a toll-free number to access the Internet while they are traveling for that department. Check with your department to see if this service has been arranged.

Finding a Wi-Fi Zone

Many major airports, hotels, restaurants, cafes, conference hosts, and other organizations now offer Internet access to travelers. While normally offered for a fee, some organizations are now offering free Internet access to their patrons. Check with the individual organization for details.

Using Blitz

The easiest way to access the new Blitz system when you are traveling is to start a web browser and go to if your account is on the cloud system, or if your account is on the on-premise system.

Library Resources for Off Campus Users via Webgateway

To connect to Library resources from off campus, use WebGateway. Log in to and click the Library Resources link. Learn more about connecting to WebGateway.

If you are accessing Library resources from a mobile device, there are a few Library resources that require an app installed on your smart phone. In those instances, you will need to use the full VPN to run those applications. See Junos Pulse for more information.

DHMC users in the name directory can access Library resources using DHMC Secure Access. For more information, and to download the Secure Access software, go to D-H Computing's Secure Access page.

Depending upon your location, some internet service providers (ISPs) may have configured their network in such a way that limits your access to information resources provided by the Dartmouth College Library. See Accessing Resources from Behind Firewalls below.

Accessing Resources from Behind Firewalls

Some Internet service providers (ISPs) use firewalls to prevent unauthorized people from accessing their network. If you are trying to access systems on the Dartmouth network from behind a firewall, the following information may allow your ISP to resolve any problems you may be having.

DND: 902 (TCP)
Mail server: 2151 (TCP)
Kerberos: 37 (TCP)
Kerberos: 750 (TCP)
Kerberos: 913 (TCP)
SideCar time sync: 37 (UDP)
