netctl and removing default routing permanently

Hi,

I have configured the following interfaces to be run at the same time with netctl: eth0 and wlan0.
I'm attempting to route all of my traffic through eth0 and to only ever use wlan0 for specific IP addresses, never as a fallback as it's connected through my phone and I don't want any accidental excess data usage.

My netctl settings for wlan0:

Interface=wlan0
Connection=wireless

Security=wpa
IP=dhcp

ESSID='xxxxx'
Key='xxxxxx'

Routes=(
        'a.b.c.d via 192.168.43.1'
        'e.f.g.h via 192.168.43.1'
)

What I'm getting with ip route:

default via 192.168.0.1 dev eth0  src 192.168.0.12  metric 202 
default via 192.168.43.1 dev wlan0  src 192.168.43.7  metric 304 
a.b.c.d via 192.168.43.1 dev wlan0 
e.f.g.h via 192.168.43.1 dev wlan0 
192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.12  metric 202 
192.168.43.0/24 dev wlan0  proto kernel  scope link  src 192.168.43.7  metric 304

The routing is working fine. I know I can run

ip route delete default via 192.168.43.1

to remove the fallback but it reappears on reconnect. Is there an easy way to make it permanent?

Thank you

Re: netctl and removing default routing permanently

I'm now also realising that the routes aren't always working.
If I manually start the profile with "netctl start <profile>" the routes are added but not on an auto reconnect after the connection was lost.

Anyone able to help me with this?
