Firewall page
Use the Firewall page to create and manage IPfilter rules.
n Input IPfilter: Manage your input filters in this section of the Firewall page.
n Routing IP filter: Manage your routing and output filters in this section of the Firewall page.
Depending on the address you provide for a filter, TransPort creates rules for either IPv4 or IPv6.
Note Because output filters are rarely needed, all output filter rules you create display with a warning
to notify you that you may not need to use an output filter rule.
See IPfilter source and destination options and IP filter criteria options for information on configuring
IPfilter rules.
