Perhaps you may configure dnscrypt to listen just lo interface, leaving
ethernet one to dnsmasq.
Another option is to configure NetworkManager connection with static
address instead of shared connection and either start dnsmasq and adjust
nftables rules from hooks or to configure other computer (you called it
"server") with static address.
On the server side, I am not sure how to configure `systemd-networkd`
DHCP/route settings to use the shared connection.
In the case of DHCP it should receive all necessary parameters from DHCP
server (dnsmasq), in the case of static network configuration set your
KDE machine (ethernet IP address) as the gateway. Debian reference has
some section on systemd-networkd.
I have set `net.ipv4.ip_forward=1` and have tried the esoteric
iptables MASQUERADE approach but I'm just not sure how all of this
ties together.
Shared connection in NetworkManager should do it for you.
Hoping for some advice!
You should provide more info
nmcli
nmcli device
nmcli connection
and check if
nmcli connection show "CONNECTION_NAME"
gives expected values (long enough output)
networkctl
networkctl status
networkctl status INTERFACE_NAME
