Firewall

The computer network in Walter Light Hall (WLH) is isolated from the rest of the Queen's campus and the World with a firewall. To access the network remotely, users must use the Virtual Private Network software client on their computer to initiate a secure communications channel.

If you are having difficulty using software that relies on network connectivity outside WLH, please contact Technical Services by initiating a Footprints request.


Network

The department's IP network provides 100Mbps network drops to offices and labs. Two gigabit fibre lines using distinct geographic routes into the building assure high bandwidth and redundancy in the event of a physical failure. All switching is Cisco gear and centrally monitored by ITServices to address any network problems as they occur. Computers that are identified as propagating viruses are shut down from the switch and the Technical Services department is notified so they may eliminate the virus from the infected computer.

The goal of the network is to provide near 100% availability and high bandwidth to users in the department.

To obtain an IP address contact Technical Services at ecetech@queensu.ca.


VPN

Effective April 30th, 2007, Virtual Private Network (VPN) will be the only way to access the WLH network resources remotely (outside of the building, including wireless access from within the building).

You can access the ECE network and Active Directory. You need to download the VPN client and read the installation instructions - available under Downloads. You will need to use your Net-ID account to login since the software and documentation are only available to members of the ECE community.

The client application runs on Windows, Mac OS X, Linux and Sun Solaris. Running the software creates a connection between your remote computer and the Queen's ECE network so you can access resources available on the Local Area Network.

IMPORTANT: You must activate your NetID before you can use the ECE VPN service.

**Please note that the instructions shown are for the Windows Download but you use these same instructions for all operating systems downloads.**

Answers

  1. There are a variety of reasons why the connection is not successful. The most common is forgetting to authenticate yourself before connecting. The link to the authentication server is found above. If you are authenticated, then try connecting repeatedly. Occasionally, the VPN server does not initiate a secure connection on each attempt, so quite often repeated attempts prove successful. Failing that, please contact Technical Services using Footprints for assistance with your particular problem.
  2. If you are trying to send mail but are unsuccessful, the best solution is to change your mail settings. Set your incoming mail server (IMAP) to "mail.queensu.ca" and your outgoing mail server (SMTP) to "mail.queensu.ca" For your outgoing server, you need to enable authentication - found under "More Settings: Outgoing Server" tab in most Outlook clients. Under the "Advanced" tab, your incoming server (IMAP) port should be set to 993, and your outgoing server (SMTP) port set to 465. You want to check both connections so you use SSL to connect. These settings will work whether you are connected using VPN or not.
  3. If you connect using VPN but get disconnected automatically, this is a normal security precaution. The VPN service will disconnect you after 120 minutes of no activity over the connection.
  4. The firewall in WLH blocks all connections - you will need to initiate a connection using the VPN client.
  5. Although you may be in WLH, the wireless network is setup so it is outside our land-line network for security reasons. As a result, if you are connected using the wireless system, you will need to initiate a VPN connection to access WLH network resources.
