How do I read the configuration setting for an ISA firewall.  Where is the deny statement for internet?
Is the ISA firewall a Bastion firewall?

ISA can be a Bastion Host if you want it to but it is more flexible if it is joined to the domain.

Unless you enter a deny statement yourself, the default rule (at the bottom) which is automatically created and can not be deleted, is a deny all statement.

You do not mention the version of ISA Server that you are running.
If it is ISA2000 then the deny rules are actioned before any of the allow rules. In ISA2004/2006, the firewall policy in the gui is read from top to bottom.
