Very basic routing and/or firewall question

Good day,

I am trying to set up a small lab with a couple small 4-5 port RouterBoards.

I am having trouble getting the routing working, and I’m not sure if it is due to the firewall filters.

I have RouterBoard1 and RouterBoard2, both have had /system reset-config no-default=yes and then IPs added directly to the ports

RouterBoard1

/ip addr add address=192.168.0.1/24 interface=ether1
/ip addr add address=192.168.66.1/24 interface=ether2

Routerboard2

/ip address add address=192.168.66.2/24 interface=ether1

RouterBoard1 ether2 port connects to RouterBoard2’s ether1 port.

PC has static IP address 192.168.0.10/24, gateway 192.168.0.1. Ethernet is plugged into RouterBoard 1 on ether1.

I can SSH in to RouterBoard1 on 192.168.0.1, and from there, I can ping 192.168.66.2. However, I cannot ping 192.168.66.2 directly from the PC.

The firewall filters are empty at the moment, but RouterBoard1, I did try

/ip firewall filter add action=accept chain=forward

with no luck.

Have I missed something obvious? I want RouterBoard 1 to route my PC to the other subnets.

I can not for the life of me find what an empty firewall filter set defaults to. Is everything defaulted to accept, or deny when you have an empty filter set?

Found the solution

Needed a static route on RouterBoard2

/ip route add dst-address=192.168.0.0/24 gateway=192.168.66.1
