Should upnp be turned off on my bridged router/modem

[revolultrablue]

I have a arris 1672g connected to a wrt1900ac. I bridged the arris. Should upnp be turned off on the arris and turned on, on the wrt1900ac?

It should be turned off for security reasons. https://www.fbi.gov/news/news_blog/cyber-tip-be-vigilant-with-your-internet-of-things-iot-devices

But if I wanted it turned on would I turn it on, on both the modem/router that's bridged and my router?

My apologies, I misread your question. I think it would be safe to turn it off for your modem and leave it on for your router.
