I seem to be missing something pretty basic here on a new Draytek 2762n.

I'm picking up the WAN IP dynamically but I also have a routed public block which is a separate range from the WAN IP. I thought I could just set this up on either LAN1 or LAN2 but it's still natting the traffic out via the WAN IP when I do so.

I've looked online and other Draytek's have the option to select 'For routing usage'. The 2762N however seems to be missing this. Surely NO NAT is allowed on this router?

Thanks

The Vigor 2762 does not support routed subnets; you will need a Vigor2862 series.
