I am new to OpenWRT and have built up my network so far, but I am stuck on one question.
First of all:
I use the Pi4 as a router behind the ISP router. (See picture)
How can a host from the manag zone be allowed to reach hosts in other zones?
I know I could share the whole zone but I would prefer to only allow hosts that absolutely need it.
Can I do this via the traffic rules?
Unfortunately, I'm not that knowledgeable about iptables rules.
Thank you in advance for your help.
