deny or reject port 137

On a linux machine that has two network cards that is running a firewall
script created by fwbuilder can having it deny traffic on certain ports
such as 137 actually increase network traffic since those machines will
be waiting for a rejection notice? I have have setup a firewall on a
Debian box and used deny and I am seeing a lot of 137 traffic I tried to
set it to reject and still saw a lot of 137 traffic the machines are
patched for welchia and blaster, any ideas?
