The problem is that pump uses a regular UDP socket (some other dhcp clients use AF_PACKET sockets), and packet sent by it are also handled by iptables. The MASQUERADE rule can't find a local IP address and drops the packet. I'm not sure how to fix it yet, reverting the patch is not a good option. --------------080006010201020805040502 Content-Type: text/plain; name="x" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="x" [NETFILTER]: Don't exclude local packets from MASQUERADING Increases consistency in source-address selection.
