Port forwarding to repeater

Hi All, I have a flint 2 on 192.168.1.1 as main wan. Connected to this is a Beryl via repeater. Beryl is DHCP ing out to 192.168.8.0 range. Can i port forward an address on the Beryl from the Flint? Flint does not see 192.168.8.0 range on portforwarding Gui. Ta

Is this the topology?
ISP Modem (LAN) --- (WAN) Flint 2 (LAN) --- (WAN) Beryl AX

If you want to access the LAN of Beryl AX from Flint2, you need to manually add static routes in Flint2.
