I have a CRS326-24G-2S+ as my main router, Eth1 is my WAN port, and Eth2 to Eth23 is my first subnet with IP 192.168.2.1 running a DHCP server on it. Eth24 has another subnet 192.168.8.1 also running a DHCP server.
Both network ranges can access the internet but can not ping each other.
I would want to access files from and to each subnet.
Well 2 subnets on the same lan (L2, network) brings some difficulties.
Same Lan here , can come with same ethernet, same VLAN, same bridge … everything that can communicate directly (L2 flat network) … is supposed to be in the same subnet.
So in your exemple the bridge with eth2-eth23 could be one subnet, with one IP range , and eth24 is a separate network (not on that same bridge, own DHCP server and subnet range
