Hi Mike,

Simply provide the cidr as the destination rather than a host. I.E. --host-route destination=192.168.0.0/24,nexthop=10.0.0.1

I assume `--host-route` works with a destination that is a single host.  Is there something I can do to establish a routing rule for a destination that is a CIDR block?

Thanks,
Mike

We use the host-route flag as mentioned above.  It makes it easy to sent internet like traffic to a gateway type of box and internal traffic to the inside for tenants that do have public access.

Hi Mike,

You should be able to update the subnet(s) and use the --host-route flag with destination,nexthop pairs. The routes get pushed via DHCP.

Is there a way to attach a routing rule to a network or subnet, with the consequence that each device attached to that net or subnet gets that routing rule?

Thanks,
