From: Philipp Hagemeister Date: Fri, 26 Sep 2014 16:11:01 +0000 (+0200) Subject: Implement on-link route adding for iproute2 X-Git-Tag: v2.4_alpha1~373 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=baa195b9884e276c4fd3dc0c9e8a84b89ea71cfb;p=thirdparty%2Fopenvpn.git Implement on-link route adding for iproute2 This is an OpenPGP/MIME signed message (RFC 4880 and 3156) Currently, when compiling with --enable-iproute2 , OpenVPN does not create a correct route when the user is connected to the Internet without a gateway (e.g. via ppp). This patch implements the corresponding FIXME.
