My guess is that this router is seeing the packets to 192.168.0.3 for some reason. My rule (-I to insert at top) will bypass your REDIRECT rule. Edmundo's question is valid. Normally a host would not go through your firewall to reach another host on the same physical segment. So my guess might be wrong. -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
