[FW1] local interface address spoofing



Hi! ,
This is a simple one. I have a Sun BOX with to interfaces (qfe0 and
trp0=token ring). At  log file I have an entry that said:
"91"  "30Dec2000"  "11:00:48"  "trp0"  "firewall02"  "log"  "drop"  "2301"
"localhost"  "255.255.255.255"  "udp"  "0"  "2301"  ""  ""  ""  ""  ""  ""
""  ""  ""  "firewall"  " reason: local interface address spoofing"  

There isnt any anti-spoofing rules configured at firewall´s interfaces...
so.. why do I have this entry? Like this one.. there is a lot, maybe too
much  = )

Any idea?
