Setup PBR to route domains used by youtubetv to wg1

Installing and Using OpenWrt Network and Wireless Configuration

I currently have policy-based routing set up on a dedicated interface such that anything connected to that interface goes to wg1 and it works great:

/etc/config/pbr

...
config policy
  option src_addr '10.9.4.0/24'
  option interface 'wg1'
  option name 'wg1 redirect'

Got me thinking why can't I setup a policy that applies to just the target device by IP and the domains I think are associated with youtubetv. Based on a tcpdump capture while using it:

googleapis.com googlevideo.com youtube.com ytimg.com googleusercontent.com ggpht.com gstatic.com

What I cannot figure out is why the following does not send the traffic from the target device to through the wg1 interface.

As a test, all endpoints DOES work:

config policy
  option name 'test'
  option src_addr '10.9.8.101'
  option interface 'wg1'

But when I add the following, I cannot see any traffic flowing through wg1 when playing videos (not cached) from www.youtube.com. What am I missing?

option dest_addr 'googleapis.com googlevideo.com youtube.com ytimg.com googleusercontent.com ggpht.com gstatic.com'

Maybe lots of necessary domains

Whack-a-mole... does it make sense to adapt /usr/share/pbr/pbr.user.netflix to use multiple google ASNs?

Yes might work
