When I try to upgrade my software from a floppy, the Cisco Secure PIX Firewall keeps going in a loop every time it tries to read the disk. What is wrong?
A. Make sure the disk is properly formatted (use the DOS command format A:), then use rawrite to put the image on the floppy. If the process fails, try the operation from a different PC. Note: Upgrade from a floppy disk is valid only for PIX Software versions 5.0.x and earlier. Q. I am installing a new Cisco Secure PIX Firewall that appears to be configured correctly. My LAN used to be connected directly to my Internet router. Now with the PIX in place, my users on the LAN cannot get out. What is wrong? A. There are a few different possibilities. • Most commonly, this is caused by corrupt Address Resolution Protocol (ARP) tables in the outside or surrounding routers. Remember that routers route to physical MAC addresses, not IP addresses, and they usually cache these Layer 2 addresses for several hours. Issue the clear arp-cache command, or reboot your device in order to clear the ARP tables on Cisco equipment. • You might also be using the same network IP addresses around your network
