sure then the l2tp would get a higher metric.
However according to the testing I ran , xl2tp make a ppp device after
establishing a connection.
when this happens , if a default gateway is present , it gives the "not
replacing existing default route to eth0" message, and doesnt add a
default route to the l2tp server. on the other hand ipsec needs a
default route to the internet when starting. this is the reason I am
changing the routing so much.

I am currently using dnsmasq as my home router supplies dns to the lan.
I will see your openresolv
