Proxy configurations for connecting to a server or blob

Proxy configurations for connecting to a server or blob

Version: 2022-11-02
Update: 2022-11-14


Domain allowlisting is a selfservice feature that is now available on myDRE. As the name implies, domains on the allowlist can be accessed from within the Workspace (you can request specific domain on the allowlist via the Accountable or the Privileged Member of the Workspace). For domain allowlisting, a proxy needs to be configured. All VMs are now automatically configured to use the proxy. However, some applications require a specific configuration to be added. 

Connect to Server via browser from within the Workspace

  1. Open a VM.
  2. Navigate to Settings in the startmenu > Network & Internet > Proxy > Manual proxy setup.
  3. If you need to connect to another VM in the Workspace, for instance because you have a VM functioning as Galaxy, RedCap server, RStudio Server, you will have to add the IP address of the VM to the exception address box. You can separate the entries with a semicolon (;). You can find the IP address of the VM below the VM (Private IP:
  4. Make sure the box Don't use the proxy server for local (intranet) adresses is checked.
  5. Do not delete the address: it will make your Z: and I: drive invisible.
  6. Press Save.

Using blob storage

  1. Follow the instructions above.
  2. Add to the exceptions address box.
  3. Press Save.

Manual proxy configurations

VMs are automatically configured to use the proxy, however if this is not the case, please find below how to manually configure the proxy.

Windows VM

  1. Manually configure proxy settings by navigating Settings in the startmenu > Network & Internet > Proxy > Manual proxy setup.
  2. Switch use a proxy server to On.
  3. Enter and port 3128.
  4. Add in exception addresses and select Don't use the proxy server for local (intranet) addresses.

Linux VM

Newly deployed Linux VMs do not currently need manual proxy configurations. If you are not able to reach whitelisted domains, please run the commands written below: 
  1. Run the following command or run it as a script:
  1. proxy=''
  2. cat > /etc/environment << EOF
  3. http_proxy="http://${proxy}"
  4. https_proxy="http://${proxy}"
  5. ftp_proxy="http://${proxy}"
  6. no_proxy="localhost,,,::1"
  7. HTTP_PROXY="http://${proxy}"
  8. HTTPS_PROXY="http://${proxy}"
  9. FTP_PROXY="http://${proxy}"
  10. NO_PROXY="localhost,,,::1"
  11. EOF
  1. Log out of the machine and log back in and configurations should be ready.
