Sounds like ports 138/139 are being blocked from your local LAN.
Check your firewall configuration to make sure that local LAN traffic is
allowed, and all external traffic is blocked except for the ports
you specifically allow.
Check the firewall logs after trying to connect to the Samba shares from
a local client, it should give you some info about what has been blocked,
and which port etc.
(Also you may want to set the "hosts allow" parameter in smb.conf to allow
only the local LAN subnet, this is a secondary security measure to the
firewall as any external netbios traffic should be blocked there anyway.)
