From d977416de1ceb9ec960b34c0202d711a9a6dead4 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 17 Oct 2012 10:18:15 +0200 Subject: [PATCH] netfilter: xt_TEE: fix routing due to rt_gateway semantic changes Since (f8126f1 ipv4: Adjust semantics of rt->rt_gateway.), xt_TEE stopped working. The problem is that it tries to ARP lookup the original destination address of the forwarded packet, not the address of the gateway.
