DNS

Domain Name Service (DNS) maps host names to IP addresses. You will
probably not need to add a DNS service icon unless you maintain a public
DNS server behind the Firebox, because outgoing UDP traffic is enabled
by default. The DNS multi-service icon allows UDP DNS traffic, as well as
TCP zone transfers to occur as specified. All of the usual logging options
can be used with DNS.
Characteristics

Filtered-HTTP

The multi-service rule Filtered-HTTP combines configuration options for
incoming HTTP on port 80 with a rule allowing all outgoing TCP
connections by default. Using Filtered-HTTP will not result in applying
the HTTP proxy rule set to any traffic. To proxy HTTP traffic, use the
Proxied-HTTP service. WatchGuard recommends that incoming HTTP be
allowed only to any public HTTP servers maintained behind the Firebox.
External hosts can be spoofed. WatchGuard cannot verify that these
packets were actually sent from the correct location. Configure
WatchGuard to add the source IP address to the Blocked Sites List
whenever an incoming HTTP connection is denied. All of the usual
logging options can be used with HTTP.
