Hi all.
This is my PIX configuration, I need deny all not interesting traffic like UDP 137 - UDP 138 - TCP 139.
I try to do it but when I add deny access-list role the ICMP traffic doesn't work.
I need to add this role on PIX.
PIX Version 6.3(2)
interface ethernet0 auto
interface ethernet1 auto
nameif ethernet0 outside security0
nameif ethernet1 inside security100
enable password xxxx encrypted
passwd yyyy encrypted

You ACL should look like this;
access-list outside deny tcp any any eq 137
access-list outside deny udp any any eq 137
access-list outside deny tcp any any eq 138
access-list outside deny udp any any eq 138
access-list outside deny tcp any any eq 139
access-list outside deny ucp any any eq 139
access-list outside permit icmp any any echo-reply
Apply the ACL to outside interface;
access-list outside in interface inside.
Hope that helps.
