To build and edit the Output Chain, select the Output tab. The output chain regulates the outbound access. If you once applied Normal firewall mode before selecting Advanced firewall mode with default policy Accept/Drop, the output chain consists of 13 default rules. If you selected Advanced firewall mode with default policy Accept/Drop while configuring the Container firewall at the first time, the output chain has the default system policy access rule only.
The default rules list is the same as in the Input Chain, the only difference being the output, instead of the input characteristic of the rules. The list of rules on this page is this:
The default system policy access rule cannot be changed as this rule decides the packet's destiny - to accept or to drop - when the packet has not any other rule to be processed by.
If, for some reason, you need to have this rule set back, click Firewall setup and select the Normal firewall mode radio button.
The attributes of the rules in the chain are described on the Building Input Chain subsection.
Here you can edit, add, delete, enable, disable, filter or move in the list any or all of the 13 default rules the output chain consists of. To edit a rule, click its name in the name column.To add a specific rule, click New Rule in the Actions group. To disable, enable or delete a rule select its check box and then click Disable, Enable or Delete. To move a rule a level up its position, click 
. To move a rule a level down its position, click 
. To filter rules by the policy, the protocol, or the current status, click the Show Search link. You can have Parallels Infrastructure Manager display only those parameters you need at the moment. To show or hide certain columns, click the Select Columns link and select the parameters you want to be displayed or clear those you do not.
You can also switch to the normal mode by clicking Firewall setup and selecting normal mode there.
