To build and edit the Forward chain, select the Forward tab. Unlike the Input and Output chains, the only default rule the forward chain has is Default system policy. Conceivably, this one is not to be edited or deleted. Instead, you are free to decide upon any number and kinds of specific rules to create and add to the Forward chain by clicking on the New Rule link in the Actions group.
After the number of rules in your Forward chain becomes bigger, you may need to sort them out. To do that, click the Show Search link and pick the three possible values from the three drop-down menus: the policy, the port, and the current status of the rule(s). 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. Click 
to take a rule a level up its current position in the chain, or 
to relocate it a level down. If two or more rules can be applied to the given packet, the uppermost rule takes priority.
The attributes of the rules in the chain are described on the Building Input Chain subsection.
To switch to the normal mode of managing the firewall, click Firewall Setup link in the Actions group.
The default forward chain policy is the policy selected on the Firewall Setup menu.
