The default configuration of the PIX is dependent on the model of firewall you have. The PIX 501 and 506E both come with basic configurations designed for SOHO and ROBO environments. The PIX 515E, 525, and 535 have no basic configuration settings; apparently Cisco figures that if you buy an expensive firewall then you had better know how to configure it!
Cisco PIX 501 and 506E Default Settings
Both models are ready right out of the box, with the following configurations set to their default settings. Tables 4.1 and 4.2 display the inside and outside default configuration settings.
Table 4.1. Ethernet 0 (Outside)
Table 4.2. Ethernet 1 (Inside)
The traffic flow is set to the default, which means that traffic is allowed to travel from the inside (100) to the outside (0) normally. Any traffic from the outside (0) to the inside (100) is not allowed, however. The enable password is blank, and the Telnet password is cisco , all lowercase.
