I disabled those rules, just in-case, but when I enable both the routes with the routing mark, all internet traffic dies. With only the Neointernet out route enabled, Napa traffic is OK but the Neo internet outbound connections are affected. I have posted my default routes below, although the ones with routing tags are disabled as is my routing to Napa.
check-gateway=ping disabled=yes distance=1 gateway=41.162.6.1 routing-mark=neoint-route
check-gateway=ping disabled=yes distance=1 gateway=169.239.44.17 routing-mark=napa-route
distance=1 gateway=41.162.6.1
