samba and smbfs

[Dave]

Hello,
    I've got a pf firewall on a box that blocks by default. I want samba to 
listen on the internal interface only, this happens, yet machines still 
can't get to the samba box. The relevant rules are below. I'm also trying to 
mount some xp shares via smbfs this too is not working probably for the same 
reason. Can someone tell me where my rules went wrong?
Thanks.
Dave.
