Hi Nicolas,

I'm using NetworkManager TUI (nmtui) to configure my connections. I'm defining two profiles WAN (enp1s0) and LAN (enp2s0). With NetworkManager I have to configure gateway and DNS information on a per-interface basis.

1. Which interface should have the gateway information ?

The WAN interface.

2. In a similar manner, which interface should have the DNS server

information ?

Neither. The DNS configuration should not normally be bound to a specific interface, so don't configure it with any interface. If you do, and that interface goes down, your DNS config also disappears.
