Subject: initiate a broadcast with dnat
Date: Wed, 09 Nov 2005 21:22:27 +0100 [thread overview]
Message-ID: <1131567747.9985.22.camel@localhost> (raw)
hello,
i want to initiate a broadcast if a udp packet with destination port
9999 reaches my router.
i have two devices: ppp0 (wan), eth0 (lan). broadcast of eth0 is
192.168.0.255.
when i use
iptables -t nat -A PREROUTING -i ppp0 -p upd --dport 9999 -j DNAT
--to-destination 192.168.0.255:9
the packet gets into the INPUT chain of ppp0 instead of the FORWARD
chain. if i use a non broadcast destination ip, the packet gets into
FORWARD chain.
is there a way to initiate a broadcast with iptables?
regards, marcel
