21.1 Legacy Series / Re: Unable to block traffic from DMZ to LAN
« on: June 03, 2021, 08:50:10 am »
Hi bitTwiddler,
Do I do not see any mistake in your rules.
When installing my OPNsense I did the following steps:
After that devices in the DMZ are not allowed to anything: DNS, internet access, access the LAN. I have to define rules where I allowed the devices in my DMZ what I want. Block by default.
So why did you change this general behavior of your setup?
Kind Regards
Thomas

When installing my OPNsense I did the following steps:
- run installation of the image via the serial console
- Assign the interface in the console: LAN and WAN
- run the wizard of the WebUI
- add the interface for DMZ
