If you are opening/forwarding UDP port range including 11211 (as e.g. in 10000-20000) and running 2.8.0.4 your instance of memcached is available remotely.
You can check access over UDP by running the following code:
echo -e 'f00k\00\01\00\00stats settings' | nc -w 3 -u YOUR.IP.ADDRESS 11211
If you would like to prevent access to your memcached from the internets, put the following in /etc/sysconfig/memcached
OPTIONS="-l 127.0.0.1"
and restart memcached.
