[syslog-ng]config option to make syslog-ng bind only to a certain IP address?

This is my first post to this list. Is there a config or command-line option to make syslog-ng only bind to a certain IP address? I have a machine with multiple IPs, and I'd like to have syslog-ng only listening on the primary IP. In the future, I may want multiple instances of syslog-ng listening on different IPs with different configs. -- Bill Moran Potential Technologies http://www.potentialtech.com
