Appendix 5 NoiseTools Internet Access
In order to function properly NoiseTools requires access to the following locations:
sms.crplc.co.uk
error.crplc.co.uk
optimus-cloud.co.uk
ics*.optimus-cloud.co.uk
optimuscloud.azurewebsites.net
cirrusics.blob.core.windows.net
s3.amazonaws.com
dev.virtualearth.net
Note: NoiseTools only uses outgoing HTTPS connections to port 443.
If you have a firewall on your PC, you will need to add NoiseTools to the list of allowed programs. This is
often automatic and you may see a prompt the first time you run NoiseTools.
If your network has other firewalls blocking outgoing connections, or if you are unable to allow NoiseTools on
your machine, you will need to contact your IT department and ask them to configure the firewall to allow the
NoiseTools program to access these locations.
If your network uses a proxy server to provide access to the internet this will need to be correctly configured
on your PC.
NoiseTools supports most proxy servers and will automatically detect these when configured in Windows, via
Control Panel > Internet Options.
If this is not configured or if NoiseTools has trouble connecting to the internet, you will need to contact your
IT department and ask them to configure your firewall to allow access.
