tests:

an array of IP addresses to ping to verify the uplinks state. You can add as

many as you wish. Predefined ones are Google DNS, OpenDNS DNS, other public

DNS. Every time an uplink is tested the IP addresses are shuffled, so listing

order is not important.

ips:

• 8.8.8.8
• 8.8.4.4
• 208.67.222.222
• 208.67.220.220
• 4.2.2.2

  functional

  base IP route table number, just need to change if you are already using

just need to change if you are already using ip policy routing, to avoid

overlapping, must be higher than 32767 (the default routing table priority,

see output of "ip rule" command)

just need to change if you are already using packet marking, to avoid

overlapping

It's normal you get such error in _detect_pppips! method, because in the configuration you specified the interface as a PPP one while it is not. See my answer to issue #19.
