Samba Error Port 137

I found few errors on the samba log file:

send_netbios_packet: send_packet() to IP port 137 failed

Packet send failed to ERRNO=Operation not permitted

Anyone know how to fix these errors

Anyway of accepting packets port 137

I am guessing this is the blue interface?
Port 137 is Microsoft Net-BIOS, for Windows file sharing, is a broadcast.
There is an option under firewall options to drop those packets on the blue interface.
