Code Issues Proposed changes

Avoid refreshing firewall rules unnecessarily.

Browse Source 
Adds a parameter to refresh_firewall allowing an array of ports to
be passed.  If an array is passed then the firewall will be refreshed
only for those ports.  If not passed, it will still refresh all
ports as it did before.
