Burp Suite

Upstream proxy servers

We first launch proxy.py using proxychains:

proxychains -q proxy
# or
python3 -m venv venv
source venv/bin/activate
pip3 install --upgrade proxy.py
proxychains -q proxy

This will generate automatically a HTTP proxy in:

127.0.0.1:8899

Now, we open Burp Suite, choose Settings, Connections and Upstream proxy servers, set the upstream 8899 proxy to compel that Burp Suite makes a request first to that server and then the proxy will process the request.

So, selecting our Burp Suite proxy with foxyproxy, we could interact with any site that our proxychains contains.
