faddr is a "foreign address" or "outside" machine. gaddr is a "global address" which is basically a NAT address. laddr is a "local address" which is being protected behind the global/NAT address. The message format generally puts the source first, then the destination. Cisco's web site has PDF documents listing every Pix syslog message with format and explanations; however Cisco changes the format and sometimes the syslog numbering for various messages. For example, the standard "built/teardown a TCP/UDP" connection messages actually changes numbers between PIX code 6.1 and 6.2, which is annoying for people who use products such as the one you're trying to create.

The Gartner Group just put Neoteris in the top of its Magic Quadrant, while InStat has confirmed Neoteris as the leader in marketshare. Find out why, and see how you can get plug-n-play secure remote access in about an hour, with no client, server changes, or ongoing maintenance.
