Requirements for Using a Firewall

The external clients and the servers within the firewall must be running SAS 6.12 TS065 or later.

The TCP/IP communications access method must be used for establishing a network connection between clients and servers.

Firewall software must be installed on the server that maintains the separation between the internal network and the Internet.

A port must be defined on the firewall server to be used as a gateway between external clients and the internal network. The firewall software must route the firewall server port to the predefined server port.

A spawner must be running on a server inside the firewall. For complete details about the spawner program, see SAS/CONNECT Spawners.
