[syslog-ng] Configuring Syslog-ng client to start on a specific IP

Hi I am using Solaris box and it has multiple IP interfaces. I need to force the syslog-ng client to run on a specific interface card i.e on a specific IP. How can I do that. Each interface card is configured to run on different subnet and they can't talk to each other. ( for security reasons ) Hence when I run my syslog-ng client I end up running on the interface where I login. I want to change it. I want the syslog-client to create a socket on the interface ( IP ) which I specify ( in the config file ). Regards Pramod
