From dc5ab2faece3b7473931357db7f63f596678481d Mon Sep 17 00:00:00 2001 From: Yasuyuki Kozakai Date: Sat, 1 Apr 2006 02:22:30 -0800 Subject: [NETFILTER]: x_tables: unify IPv4/IPv6 esp match This unifies ipt_esp and ip6t_esp to xt_esp. Please note that now a user program needs to specify IPPROTO_ESP as protocol to use esp match with IPv6. This means that ip6tables requires '-p esp' like iptables.
