Read the thread "Multiple NICs" from earlier today.
I just changed my smb.conf at my customerŽs site to use 2 NICs.

Just leave the interfaces-option away and it will use all NICs except

For "hosts allow" use something like:

hosts allow = 192.168.16.

to just let in the local C-class-hosts. (Note the trailing dot)

IŽm right now monitoring the log.?mbd-files on that host and it works
like a charm.

You can verify the usage of both (or all) NICs via

"smbclient -L sambaserver"

it will list the used interfaces first. And you will hopefully notice
the increased performance ;-)
