We have a Cisco PIX 515e running cisco os V6.3.5. Our goal is to add a line of code(logging permit-hostdown) so the PIX will allow inbound and outbound traffic and not stop functioning when the syslog server is unavailable to the PIX 515e. So far, it doesn't look like 6.3.5 supports the PERMIT argument in the LOGGING command. Is upgrading the os on the PIX the solution or is there another way to keep alive internal Internet access even when the PIX can't write or access the syslog server? We're using the latest version of Kiwi for our syslog server.
