16 Are you sure that your routers do not respond to the default source address
17 0.0.0.0 arping request? Have you tried changing this to:
18
19 gateways_eth0=( "192.168.1.254 192.168.1.1" )
20

69 The option -0 negates the -S 192.168.1.114. Use one or the other.
70
71 If it works with option -0 then use my suggested format for gateways_eth0=
72 because you do not need to spoof the arping address.

74 HTH.
