If you want to bypass the Sucuri firewall and access your site directly (for testing or development purposes), you can do so by configuring your local DNS to use the real (Internal) IP address of your site, instead of your Sucuri firewall IP address.
Finding your Real (Internal) IP
Go to your Sucuri firewall dashboard page. In the main site page you will see an entry with your websites and the hosting IP address of each one. Depending on whether your website list is in card or list format, it will look like this:
Manual editing hosts file
You can modify your
/etc/hosts on Unix-like systems or
%SystemRoot%\system32\drivers\etc\hosts on Windows to bypass the DNS for your site. You will need to add a DNS modification into that file telling your personal computer that your site is located at yourr (real) hosting IP.
# /etc/hosts 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback 66.xx.xx.78 www.example.com example.com
66.xx.xx.78 is your real IP address and
example.com is the domain of your website.
This good article by Rackspace explains how to modify the hosts file file on multiple operating systems.
