# 9001 is the port Tor will use for relaying traffic through. 
# 9030 is the port used for the global Tor directory.

ORPort 9001
DirPort 9030

# These basically determine how much to throttle traffic. 
# 770 Kilobytes per second should keep us from burning through our 
# 2 TB per month cap too quickly.

# 2 TB (2000 GB) is the max amount of bandwidth we can use since 
# that’s the cap DigitalOcean has per month for this plan.
# We’re leaving 1GB out for things like software updates, etc.

# This means your relay will WON'T be an exit relay. Running an exit 
# relay is the most hardcore of relay operation and will get you 
# lots of high fives from hackers but also legal threats from the 
# RIAA/MPAA/FBI/DEA/KFC/Interpol/Scientology/Everyone.
# Running a non-exit relay shouldn’t get you much attention.
