# These notes explain how I built an open source Ubuntu ISO server.
# ISOs are large files that are needed to install open source software.
# These notes are updated frequently and I use them each time I
# rebuild my server.
#
# Because linux is free, using my computer to share various linux
# ISOs helps the open source community. To do this, I am using the
# torrent protocol. The torrent protocol allows anyone with an Internet
# connection to help. 
#
# WARNING:
# The purpose of this document is to share linux ISOs. Using these
# commands for anything other than sharing open source software is
# strictly prohibited.
#
# In fact, this document is not a guide at all. This gist exists soley
# as my own personal notes. You do not have authorization from me to
# follow these notes. Do not use this document for anything.

# otherwise. You have been warned!

# Allow ports through ufw (required in newer versions of Ubuntu)

ufw allow 18000:18100/udp
ufw allow 137

# Recommended:
 - Set a static IP on the isohost OR static DHCP lease on your router
 - Forward ports 18000-19000 TCP/UDP to the IP of the isohost
