# For example, I have a redis container, I want it only serve for specific IP addresses: 172.31.101.37, 172.31.101.38
$ docker run -d -p 6379:6379 redis:2.8

# After start redis container, the iptables looks like this:
$ iptables -t filter -nL
Chain DOCKER (1 references)
target     prot opt source               destination
ACCEPT  tcp  --  0.0.0.0/0            172.17.0.2           tcp dpt:6379

# Get the IP address of redis container
