Preference for helper specs?
# Option 1:
# Use content to separate the helper from the spec
it "should have something" do
content = helper.some_helper_method
content.should have_tag('a', :text => 'foo')
end
# Option 2:
# Combine helper call and spec

First things first, you want to make sure that all of your iptables chains are set to ACCEPT, otherwise, you might lock yourself out of the system by blocking the SSH port.

sudo iptables -P INPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -P OUTPUT ACCEPT

Next, you can flush your chains to start from scratch.
