help configuring opnsense, now

I need to configure 3 lan networks
each one with its own wan connection (i have 3 isp)
and each lan with its own dhcp range
(i have 6 ethernet cards)

For now I managed just to configure 1 lan
and the 3 wans are working
but the other 2 lans are not working

i did create the rules in firewall ->rules
but the other 2 lans can't ping the gateway
