BlazeMeter has not 1, not 2 but 3 options for behind the firewall load tests.
1. You can whitelist our IP addresses
Whitelisting is a fast and easy option to implement.
What is whitelisting?
If you have to work behind a firewall then whitelisting a certain IP will tell the firewall to allow requests from that IP (or ip range) into the network as “safe”.
Generally, items are blacklisted for security purposes and the firewall is configured to block everything. You can contact your security or network administrator to better understand your company policy regarding whitelisting internet IPs
BlazeMeter IP addresses are available on-demand for the load engines.
2. You can purchase your very own dedicated IPs and use them to your heart’s content.
If your network security policy does not allow a vast range to IPs to be whitelisted, then you can buy dedicated IP's and set your server to use them.
This option is best in small numbers because you’ll need an IP for every server (console+ engine).
3. On Premise Testing
BlazeMeter’s On-Premise Solution can run within your company’s network.
It does require servers (physical or virtual) installed on your private network.
The system prerequisites for downloading the agent are simple:
Be able to download files into the load engine from the internet over http/https.
After installing the files, you can choose any cloud geo-location as well as your Private Locations, and your own servers will be used to create the load.
