14.3 Services
WinRoute services enable the administrator to define communication rules easily (by permit-
ting or denying access to the Internet from the local network or by allowing access to the local
network from the Internet). Services are defined by a communication protocol and by a port
number (e.g. the HTTP service uses the TCP protocol with the port number 80 ). You can also
match so-called protocol inspector with certain service types (for details see below).
Services can be defined in Configurations
