dhcpcd-discuss

Thanks Roy for dhcpcd , openrc and the help here,

After applying the dhcpcd fixes^ (see below) I get this line in
/var/log/messeges:

pppd "not replacing existing default route to eth0"

to verify its dhcpcd I run:
dhcpcd -k eth0 && dhcpcd -d -C 60-l2tp.conf eth0
then /etc/init.d/strongVpn start
and got a l2tp connection established:
# ip ro
98.158.112.57 via <WAN_GW> dev eth0 
98.158.yyy.xxx dev ppp0  proto kernel  scope link  src 98.158.yyy.xxz
192.168.14.0/24 dev br0  proto kernel  scope link  src 192.168.14.70 
<MY_SUBNET> dev eth0  proto kernel  scope link  src <MY_IP>  metric 203 
127.0.0.0/8 via 127.0.0.1 dev lo 
default via 98.158.117.129 dev ppp0 
default via <WAN_GW> dev eth0  metric 203 


how can I fix this?
