WIFIs manage on local, not CAPsMAN.

Build the LAN side

  # Create the LAN bridge
/interface/bridge add name=lan protocol-mode=rstp
 
# Put your Ethernet uplink to the switch into the LAN bridge (adjust ports as needed)
/interface/bridge/port
add bridge=lan interface=ether1

Give the LAN an IP + DHCP server

# Give the router a LAN IP and a small DHCP server (optional but typical)
# Use the subnet you like; 192.168.88.0/24 shown here
/ip address add address=192.168.88.1/24 interface=lan
/ip pool add name=dhcp_pool_lan ranges=192.168.88.10-192.168.88.254
/ip dhcp-server add name=dhcp_lan interface=lan address-pool=dhcp_pool_lan
/ip dhcp-server network add address=192.168.88.0/24 gateway=192.168.88.1 dns-server=192.168.88.1
/ip dhcp-server enable dhcp_lan

Configure Wi-Fi station to wahoo (open, hidden)

/interface/wifi set wifi1 ssid="wahoo" mode=station disabled=no

Get WAN IP via DHCP on wifi1

/ip/dhcp-client add interface=wifi1 use-peer-dns=yes add-default-route=yes

NAT + basic firewall

  /interface/list add name=WAN
/interface/list/member add list=WAN interface=wifi1
 
/ip/firewall/nat
add chain=srcnat out-interface-list=WAN action=masquerade comment="WAN via wahoo"
 
/ip/firewall/filter
add chain=input action=accept connection-state=established,related
add chain=input action=accept in-interface=lan comment="manage from LAN"
add chain=input action=drop in-interface-list=WAN comment="drop unsolicited from WAN"
 
add chain=forward action=accept connection-state=established,related
add chain=forward action=accept in-interface=lan out-interface-list=WAN
add chain=forward action=drop
