Reblaze Setup Checklists

Easy-to-use checklists for starting and testing Reblaze
An update is pending for this section for v2.14.

Overview

Please go through these checklists, and verify that their actions have been completed, both before and after your traffic is routed through Reblaze.
There are three checklists below: two for setup, and one for testing.

Prerequisite

Before going through the checklists below, you should already have performed the actions listed in Getting Started.

Configuring your environment

Item
Action
More Information
Web Server Firewall
& Hosting Firewall
Verify that Reblaze IPs are whitelisted in the firewall.
Also, please ensure that only Reblaze IPs are able to access your web server, i.e. block access for all non-Reblaze IPs. This can be done via a set of rules for your firewall, or via .htaccess files.
Rate Limits
Verify that you're not using any Rate Limit/QOS rules that apply to Reblaze IPs.
This avoids potential blacklisting of Reblaze, and other availability issues. (If Rate Limits are applied, Reblaze can be misidentified as a DDoS source.)
Website Cache Settings
Ensure that each site/application returns the correct caching instructions.
You can also control caching behavior through Reblaze using Cloud Functions.

Setting up Reblaze

Item
Action
More Information
Upstream Server
Verify that the settings for each domain/site are correct.
Servers are defined in Backend Services. Security policies are assigned to domain/site URIs on the Web Proxy page.
SSL
Verify that your SSL setup (which should have been performed already, as described in Getting Started) is complete before routing traffic to Reblaze. (Note that if you want Reblaze to generate Let's Encrypt certificates for you, the traffic must be routed to Reblaze before the certificate can be generated.)
You can use pre-existing certificates, or generate new ones via Reblaze. More info.
Non- Browser Applications
If your application serves bots or other non-browser clients (e.g., monitoring services, mobile/native applications using an API, etc.), you will need to exempt them from Reblaze's browser challenges.
Mobile/native applications are exempted by using the Mobile SDK.
For other non-browser clients, you should disable Active Challenges. It is highly recommended that you enable Passive Challenges to replace them. More info on the overall challenge process is here.
Web Application Firewall (WAF)
Review the default ACL Policy and WAF/IPS Policy, to ensure they meet your needs. If more customized rulesets are needed, define new Policies.
The Policies are assigned to URIs within the sites/domains in the Security Profiles section of the Web Proxy page.
Block Known Sources
Reject traffic from sources known to be hostile (e.g., IPs, countries, etc.)
Lists of sources are selected/defined in Session Profiling. Their associated tags are included within ACL Policies with an operation of "Deny".
Whitelist Known Sources
Exempt specific traffic sources from inspection and filtering.
Lists of sources are selected/defined in Session Profiling. Their associated tags are included within ACL Policies with an operation of "Allow" or "Bypass".
DDoS Settings (Rate Limits)
Review the rate limits to ensure they match your site's capacity. For most use cases, the default settings should work well.
Some settings are in Advanced Frontend Settings; others are in Dynamic Rules. More info about this.
Alerts
Review and customize alerts and notifications according to your needs.
Done within the Planet Overview.
Account
Review your account settings to ensure they are correct.
Sometimes new customers enter placeholder values at first. Ideally, correct values would be in place by the time Reblaze is active.

Testing your setup

When the following checklist has been completed, you'll be ready to go.
Note: by default, Reblaze is deployed in Report mode for all applications. In this mode, it will not block traffic; it merely reports on the traffic it would have blocked, if that application had been set to Active mode.
Item
What to verify
More Information
Check DNS
Run a DNS query for the website, and validate that the DNS records of the HTTP/S services are pointing to Reblaze CNAME /IPs only.
You can use tools such as https://dnschecker.org/.
Test Traffic
Generate traffic to your site, and verify that it is being displayed in the Dashboard. For more in-depth traffic inspection, you can use the View Log. If SSL traffic is used, use your web browser to validate that the right certificate is being used.
Both the Dashboard and View Log include a Query box to filter their displays. Here's how to use the Reblaze Query Box.
Test Non-Browser Clients
If applicable, generate and test traffic from non-browser clients, and verify via the Dashboard that the requests are not blocked/reported.
This is to validate the (optional) settings configured for non-browser clients, as described in the checklist above.
Monitor and Optimize Settings
As traffic is processed by Reblaze, review the Dashboard (and ideally, the View Log) to see the decisions that are being made. Optimize Reblaze until it is performing as expected. Once you are satisfied with Reblaze's traffic scrubbing, move your application(s) from Report mode to Active mode.
Reblaze's logs are a rich source of insights into incoming traffic. Highly recommended reading: Understanding and Diagnosing Traffic Issues.
