Communication between 2 Lans

Hi, I work on a labo under Workstation.
I have 3 interfaces on my OpenWRT:

  • a LAN Network (lan segment)

  • a WAN Network (NAT)
    -a DMZ network (Lan Segment)

  • The Lan can access to Internet via the WAN

  • The DMZ can access to internet via the WAN

BUT, LAN and DMZ don't communicate and I don't find why.
Could you help me ?

From your screenshot, it would appear you have things correctly configured. But there could be more to the story, so let's look deeper.

Please copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:

cat /etc/config/network
cat /etc/config/dhcp
cat /etc/config/firewall

Also, check the local firewalls on the hosts in question. Windows, for example, defaults to only allow connections from other hosts on the same subnet, and it will reject attempts from other subnets.
