Firewall Rules for DMZ-Based Security Servers
DMZ-based security servers require certain firewall rules on the front-end and back-end firewalls. During
installation, View services are set up to listen on certain network ports by default. If necessary, to comply
with organization policies or to avoid contention, you can change which port numbers are used.
IMPORTANT For additional details and security recommendations, see the View Security document.
Front-End Firewall Rules
To allow external client devices to connect to a security server within the DMZ, the front-end firewall must
allow traffic on certain TCP and UDP ports. Table 5-1 summarizes the front-end firewall rules.

TCP 80 (Optional) External client devices connect to a security server
within the DMZ on TCP port 80 and are automatically
directed to HTTPS. For information about the security
considerations related to letting users connect with HTTP
rather than HTTPS, see the View Security guide.
