[Openvpn-devel] NOTE: unable to redirect default gateway -- Cannot read current default gateway from system

[Thomas S. <tsc...@t-...>]

Hi,

In case of being totally wrong here, please redirect me to the right 
place (bug-systems, forum,...).

Some words about the configuration:

Server: shares a private IPv4-Network and ula-IPv6-Network
IPv4-Adresses also NATed to the public.

proto udp6
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem
server 192.168.178.128  255.255.255.128
server-ipv6  fd00::1:1/112
push "route 192.168.178.0 255.255.255.0"
push "route-ipv6 fd00::/64"
keepalive 10 120
verb 3


Client:
client
dev tun
proto udp6
remote raspberrypi.XXXXXXXX.myfritz.net 1194 udp6
ca ca.crt
cert client.crt
key client.key
remote-cert-tls server
redirect-gateway
verb 3

This works perfectly as long the client has still an IPv4-connection.

But in case of an IPv6-only-client (not system-wide disabled, just not 
getting IPv4-addresses by the ISP, e.g. eduroam-IPv6) the client doesn't 
set the IPv4-default route, since it can not find the old one.

Regards,
Thomas
