Updating firewalls

- a list of destination ports or port ranges to which the rule applies may optionally be specified.

If no port or port range is specified, the rule applies to all destination ports.

You can ask the firewall which profile it's currently using by typing .

Early versions of SP2 offered three basic operating modes for the firewall: On, Off, and Shielded.

This way, you can throw whatever traffic you want at your network, and the logs will be easier to parse.

Also, this allows you to send different types of traffic down range without interfering with legitimate network traffic.

The firewall offers some really basic protections on your server - it's a very important tool.

If a network traffic generator is not on hand, place the firewall in an operational environment, but gradually change the settings throughout a given time period.Well, this is highly contingent upon what you mean by test.If you're testing whether your firewall is blocking or recording the types of traffic for which it is configured, perform the test when network traffic is at minimum activity.For example, to create a rule that allows TCP traffic through port 80 and ICMP traffic: A list of IP address blocks that are allowed to make inbound connections that match the firewall rule to the instances on the network.The IP address blocks must be specified in CIDR format: If a packet has passed all other rules without matching, it will reach this rule, which says to DROP the data.
