Can someone provide a list of TCP ports which must be open in the
outgoing firewall settings, so Cygwin setup.exe can fetch data from
mirror.kernel.org?
You should not just use the US default mirrors.kernel.org on the west coast in
San Jose, California, near San Francisco, California, but choose the closest
reliable mirror(s) to your system from the mirror list:
https://cygwin.com/mirrors.html
Ports required depend on which services and transport protocols are supported by
each mirror you use, and are the standard ports for those services and protocols:
$ grep '\(^ftp\(\s\|-\)\|^https\?\s\).*/tcp' /etc/services
ftp-data 20/tcp #FTP, data
ftp 21/tcp #FTP. control
http 80/tcp www www-http #World Wide Web
https 443/tcp MCom #HTTP over TLS/SSL
