Pulling my hair for days here setting up DNS and DHCP with dnsmasq and the new way of doing things with netplan.

WAN-router is on 192.168.0.1 - works fine



LAN-router is on 192.168.1.1 - DHCP works fine, handing out 192.168.1.x addresses as it should. Can ping google.com



Client laptop is on 192.168.1.181 - Gets IP, can ping LAN-router, can ping IP addresses directly (such as 8.8.8.8) but traceroute and DNS does not work

This is my dnsmasq config:

bogus-priv

strict-order

filterwin2k

expand-hosts

domain=home

no-resolv

listen-address=127.0.0.1

listen-address=192.168.1.1

#DHCP range

dhcp-range=192.168.1.1,192.168.1.254,72h

dhcp-option=option:router,192.168.0.1



# Upstream name servers

server=192.168.0.1

server=8.8.4.4

server=8.8.8.8

Status of dnsmasq, boots fine:

I'm sure I've confused it along the way. I was able to DNS resolve for names from the client laptop for a while, but no actual data transport was possible, so wasn't possible to actually reach the internet practically.

It's all a bit new to me so would appreciate any pointers.
