Had hoped there would a way for the clients to utilize the
    endpoint node's DNS resolver.


There are many ways to do that. You could setup post-up scripts that modify resolv.conf when the wg interface is up. You could run a caching dns server on your lan that talks to your gateway dns resolver.

I am utilizing unbound as DNS resolver on the endpoint node and thus in the resolv.conf the nameserver reads 127.0.0.1. The lan peers are not local on the endpoint node but connecting remotely over inet. Thus was my question whether WG has a mechanism to tell the lan peers to use their own DNS resolver or the DNS resolver of the endpoint node. Understanding now each WG uses its own resolver setup. Perhaps got confused with the WG's Android app requiring the input for setting a DNS resolver.


    forwarding is enabled in the kernel. Currently I am trying to set
    it up  with the name space solution
    (https://www.wireguard.com/netns/
    <https://www.wireguard.com/netns/>) which perhaps do not require
    iptable rules, at least there is no mentioning of it.


I have not played with netns, so I cannot comment on that.

The name space solution did not work out. eth0 (and its public ip)  vanished into the namespace (physical), suppose that is intended (by the way of the tutorial). Subsequent inet connection is gone (till netds del physical) and thus the endpoint is not accessible anymore remotely over the inet. Maybe I am missing something, that is way I set it up:

# The loopback network interface
auto lo wg0 eth0
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
    address <endpoint node public ip>
    netmask 255.255.255.255
    broadcast <endpoint node public ip>
    network <endpoint node public ip>
    gateway <ISP gateway ip>
    # dns-* options are implemented by the resolvconf package, if installed

iface wg0 inet static
    address 192.168.120.1
    pre-up ip netns add physical
    pre-up ip link set eth0 netns physical
    pre-up ip -n physical addr add 192.168.12.52/24 dev eth0
    pre-up ip -n physical link add wg0 type wireguard
    pre-up ip -n physical link set wg0 netns 1
    pre-up wg setconf wg0 /etc/wireguard/wg0.conf
    up ip link set wg0 up
    post-up ip route add <ISP gateway ip> dev wg0
    post-up ip route add default via <ISP gateway ip>  dev wg0
    post-up sysctl -w net.ipv4.ip_forward=1


    Being a of peer-to-peer concept WG is then not really suited as
    VPN gateway?


It certainly is suited for tunneling all traffic through the tunnel. There are a few blog posts around describing how to do this.

Worked my way through a lot of those and haven't got it working, that being the cause of initiating the submission to the mailing list.
