Port Forwarding in Mavericks

---

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

####1. anchor file Create an anchor file under /etc/pf.anchors/<anchor file> with your redirection rule like:

richhollis

tables = [] # or ActiveRecord::Base.connection.tables
collation = "utf8_unicode_ci"
char_set = "utf8"
db = "your_database_name"
# write out
puts "USE #{db};"
puts "ALTER DATABASE #{db} CHARACTER SET #{char_set} COLLATE #{collation};"
tables.each do |t|
  puts "ALTER TABLE #{t} CHARACTER SET #{char_set} COLLATE #{collation};" # changes for new records
  puts "ALTER TABLE #{t} CONVERT TO CHARACTER SET #{char_set} COLLATE #{collation};" # migrates old records
