Section 5.17
Managing Firewalls
Firewalls are software systems designed to prevent unauthorized access to or from private networks. Firewalls
are most often used to prevent unauthorized Internet users from accessing private networks (Intranets)
connected to the Internet.
When the ROX II firewall is enabled, the router serves as a gateway machine through which all messages
entering or leaving the Intranet pass. The router examines each message and blocks those that do not meet the
specified security criteria. The router also acts as a proxy, preventing direct communication between computers
on the Internet and Intranet. Proxy servers can filter the kinds of communication that are allowed between two
computers and perform address translation.
NOTE
In general, the ROX II firewall implementation will maintain established connections. This applies
when adding, deleting, or changing rules, and also when adding, deleting, or changing policies. When
applying new, or modified, rules or policies, previous traffic seen by the router might still be considered
as having valid connections by the connection tracking table. For instance:
.
A rule for the TCP and UDP protocols is applied.
.
The router sees both TCP and UDP traffic that qualifies for NAT.
.
The rule is then modified to allow only UDP.
.
The router will still see TCP packets (i.e. retransmission packets).
