Hi,
I found something strange in my iptables log. It was strange because I put my server at ISP and I don't know why there was an internal IP logged by my server.
May 2 16:55:35 ABC kernel: FW-REJECT IN=eth0 OUT= MAC=ff:ff:ff:ff:ff:ff:00:10:5a:63:d3:d8:08:00 SRC="" DST=255.255.255.255 LEN=276 TOS=0x00 PREC=0x00 TTL=128 ID=34884 PROTO=UDP SPT=68 DPT=67 LEN=256
How can I block these kind of IP?
Thanks,
Keith
