I want to disable NAT because I use the Omnia behind a Cable Router which doesn’t support bridge mode.
Is there a possiblility to bridge all Ports of the Omnia and also use the DNSSEC Service also the OpenVPN Service ?!
The DNS with validation etc. is independent of NAT and routing/VPN. You only need to somehow point clients to resolve via Omnia, and by default that’s done via DHCP from Omnia. I’ll better not try answering other parts of the question.
