From b00da24550b39a2cc95ec74de5224da8e2e2dabe Mon Sep 17 00:00:00 2001 From: Alejandro Enrique Date: Wed, 11 Feb 2015 11:02:45 +0100 Subject: [PATCH] add host route on local ip arp request This patch fixes relayd not adding a host on an ARP request for the local IP address. When relayd is launched using the -L option, it was not adding the necessary host routes when it receives an ARP request for the local IP address. This issue makes a host not able to connect to the device running relayd until there is ARP traffic involving a third host.
