NAT Reflection for remote (not directly attached) network

[d4rkd3n1337]

Hello, folks

I see in mans that NAT reflection works only for directly attached networks.

I have next scheme:
OPNsense gate, watching to WAN network and have LAN network (10.1.1.0/24).
Cisco gate, one port attached to 10.1.1.0/24 and hame self networks (172.16.1.0/24 etc)

with nat reflection I perfectly can connect to WAN_IP:80/443 etc from any host 10.1.1.0/24
but from remote local net (ex. 172.16.3.0/24) I cant reach WAN_IP.

What manual rule I must create in outbound NAT?
