CHAPTER 4: Types of Services

WatchGuard Firebox System
you must explicitly enable (by adding service icons) any outgoing services 
you intend to use. If you do not, outgoing TCP connections won’t work 
properly.
Characteristics
Protocol:  TCP
Server Port(s): 80 (although servers can be run on any port, a common 
alternative is 8080, and Secure Socket Layer (SSL) connections are 
generally served on port 443)
Client Port(s): greater than 1023 
RFC: 1945
Common Scenarios
Scenario 1
Description
“Public” HTTP server on the optional network.
Icons in the Services Arena
An HTTP icon, with Incoming From Any to the HTTP server.
Scenario 2
Description
“Public” HTTP server on the trusted network.
Icons in the Services Arena
Even with dynamic NAT, the HTTP server must have a “public” 
address. Configuration is exactly the same as in Scenario 1.
Proxied-HTTP
Proxied-HTTP combines configuration options for HTTP on port 80 with 
a rule allowing all outgoing TCP connections by default. Using the 
Proxied-HTTP rule ensures that all outgoing HTTP traffic, regardless of 
port, will be proxied according to the HTTP proxy rules.
WatchGuard recommends that you allow incoming HTTP only to any 
public HTTP servers maintained behind the Firebox. External hosts can be
