Hi,
An example of setup could be:

fiber---> OPNSENSE router/gateway/dhcp server/firewall (192.168.1.1)  
                                     |
                                     |_  connect to the WAN port of ->  ASUS wireless AP/ dhcp relay 

That way clients connected on the router and clients connected on the wireless AP will be on the same
network 192.168.1.0 and can communicate between them. This is the simplest setup.

Another example of setup could be:

fiber---> OPNSENSE router/gateway/dhcp server/firewall (192.168.1.1)
                                     |
                                     |_  connect to the WAN port  of ->  ASUS wireless AP (192.168.2.1)/dhcp server

That way clients connected to the router and clients connected to wireless AP will be on different networks
192.168.1.0 and 192.168.2.0 and could be separated if desired depending on firewall rules.

I would go for example n° 1 KISS.

So first connect your box to the OPNSENSE box and set it up to be 192.168.1.1.
If you want your box to have always the same IP address reserve a range of
ip addresses in the dhcp setup for static assigned ip addresses or use the
bind ip to mac feature.
When you can easily access the OPNSENSE box web interface connect
the fiber to the OPENSENSE WAN port and setup and test connection.
Then connect the ASUS wireless WAN PORT the a OPENSENSE LAN port.
If you can access the ASUS web interface set ip up as DHCP relay,
otherwise connect directly to a ASUS LAN port to set it up.
WIFI settings could stay the same.
Hope that I did not forget any essential step (but I probably have)
and that it helps you somehow.

Ciao,
Tito
