# Ephemeral Port Range
# Reverse proxy connections will use these ports for the client
# sockets. If the server experiences port exhaustion, upstream
# connections may need to be limited or a new reverse proxy host
# may be needed.
# NOTES
# - Do not operate any application listeners within this range.
# RECOMMENDATION
# - Set if experiencing ephemeral port exhaustion on client
#   connections.
# - Consider a range that's easy to remember, like 10000-65535.
# SEE ALSO
# - none
