To enable the display
of Web pages when a firewall exists between desktop computers and
the computer that is hosting SAS, a firewall rule must be added that
allows a Web browser to connect to SAS. The firewall rule specifies
a range of network ports for which SAS remote browsing connections
are allowed. Contact the appropriate system administrator who can
select and configure a range of network ports for remote browsing.
The range depends on the number of simultaneous SAS users. A value
of approximately three times the number of simultaneous SAS users
should reserve a sufficient number of network ports.
After the firewall rule
is added, SAS must be configured to listen for network connections
in the network port range. Normally, SAS selects any free network
port, but the HTTPSERVERPORTMIN and the HTTPSERVERPORTMAX system options
limit the network ports that SAS can select. Add these system options
to your SAS configuration file. Set HTTPSERVERPORTMIN to the lowest
port in the network range. Set HTTPSERVERPORTMAX to the highest port
in the network range. For example, if the system administrator defined
a network port range of 8000 to 8200, the system options would be
the following:
httpserverportmin=8000
httpserverportmax=8200
After these system options
are set, desktop computers can display Web pages. If there is an insufficient
number of network ports, or the system options are specified incorrectly,
a message appears in the SAS log.
