Good morning I'm writing you because are several days that I find session like below, in the log of my Pix Firewall ver.6.3(3):
Feb 20 14:11:37 pix1a-inside pix1a %PIX-4-106023: Deny udp src dmz-zcom2: my_public_ip_address:/137 dst outside:0.0.1.66/137 by access-group "acl_dmz-zcom2"
Can you help me to understand what happen?
Seems like that a host make spoofing of its IP address.
Any information that you can send me are welcomed.
