kodi no route to default gateway

I hope this post is at the correct forum
I have one old version firestick (without voice control) that kodi and all other apps that are able to access the internet
I recently purchased two of the newer models ( with voice control)
I am able to down load kodi 17.3 on both the newer models.
I can see the firestick ip and mac in the arris tg1682g device list
I’ve reset the router, deinstalled/reinstalled kodi on the two that kodi is unable to access remote hosts on the internet
basically the arris ip v4 gateway is set to 10.0.0.1/24
the two new firesticks have kodi on 192.168.49.1

the info below tha is italized is for the working device
and the info in BOLD is one of the new ones not working for kodi to access remote hosts on the internet

I have many years support global networks… including the latest push to switch to Ethernet Virtual Private Line…

but i have not have much time in working with the software side…. i have done some work with unix and linux but that was many years ago

Is there some where in kodi that i can modify a config file to get these two devices to route to 10.0.0.1 gateway?

Thanks in Advance
Greg
