I connect directly (lan cable) to rutx09 router.
I can access devices which are on rutx09 internal subnet (192.168.1.0/24).
I cannot access devices which are on other internal subnets (Example: 192.168.20.0/24) in my network.
I can ping devices on my other subnets.
Traceroute also works.
This should mean that static routing is configured properly.
In Network-> Firewall:
1) General Settings, all (Input, Output, Forward) is set to Accept.
2) Zones, firewall rule lan => wan, all (Input, Output, Forward) is set to Accept.
All firewall rules in rutx09 are default rules. No other rules have been added.
What am I missing here?
