As we know Scrapy runs on port between 6023 to 6073.
But due to firewall these ports are blocked and I am abideby by it.
Now I am trying to change the port of scrapy.
To something like 127.0.0.1:80.
Scrapy itself is a framework, it does not listen to anything per-se.
You seem to be refering to the telnet console.
See TELNETCONSOLE_PORT
setting to change the port it listens to.
Something like this should do what you want:
TELNETCONSOLE_PORT = [80]
