Welcome I do not know where is the problem with my firewall set I have set :
iptables -t filter - I FORWARD -j LOG And because of this smth like this is displayed on my screen BAD_FORWARDIN=eth2 OUT=eth0 SRC=169.254.199.81 DST=148.81.116.98 LEN=69 TOS=0x00 PREC=0x00 TTL=127 ID=34055 PROTO=UDP SPT=137 DPT=53 LEN=49 This is strange because eth2 ip is 192.168.2.254 so if the src ip of this packet is 169.254.199.81 this means that someone is having fun. I want to know what machine is sending this packets, so I set iptables -t filter -I INPUT -i eth2 -s 169.254.199.81 -j LOG but it doesn't help I see logs from FORWARD rules but i do not see any from INPUT rules. This was a shortcut of my firewall rules, but the meaning of this hole problem has been shown to you Can someone explain me this? -- ROBERT MAGIER
