Message-ID: <41372A24.3020006@mrassociates.com> (raw)
I was working with DNAT and I can successfully send a traffic to another
machine. The problem is that broadcast traffic is not routed. So I added:
iptables -t nat -A PREROUTING -p udp -d 192.168.1.255 --dport 3000 -j
DNAT --to-destination 172.16.17.21
This is the only rule. But nothing is seen by the remote machine.
Normal traffic is routed correctly.
My guess is that even though the IP address has been changed the MAC
address has not and that is what is causing the packet to not be routed.
Correct? Is there a way to do this?
