oFono tells ConnMan to set the gateway to 10.35.243.229. At the same 
time it tells to user 'Method=static Address=10.35.243.229'. That 
confuses the plugin/ofono.c code I guess. Could it be that the Address 
should be something else?

Thanks. That was the ofono output though :)

Hmm, best thing is to take this to the ofono mailing list. I don't I can 
help you here.

Thanks,
