Hi Neil,
thanks for the reply ... yes, I want to start it, if eth0 goes up.
Ok, it will probably work (not tested yet), but ...
it's not a big difference if it is in local.start,
postup() function or some another script.)
I feel that's not the right way how it should be done.
This is probably a bit closer to rc-script author idea:
modules=( "iptunnel" ) # no info about it in net.example
iptunnel_vpn0=( "mode gre remote 1.1.1.1 local 2.2.2.2 dev eth0" )
config_vpn0=( "3.3.3.3" )
postup(){
[ ${IFACE} == "vpn0" ] && ip link set vpn0 mtu 1420 up
}
Next I like to add this route:
ip route add 4.4.4.0/24 dev vpn0
which IMO should be possible to write as:
routes_vpn0=( "4.4.4.0/24" )
but it fails with "[!!]" error, which tells me exactly nothing
Any idea ?
