OpenWRT to specify traffic routing for a specific interface?

Question

VPN

OpenWRT :
WAN => 217.19.XX (white IP)
WireGuard.Server => WAN => 62.221.XX (white IP)
LAN connected to it WLAN1 192.168.1.0/24 (AP1)
LAN2 is WireGuard Client 172.16.100.4/32 ( gateway 172.16.100.1/24)
LAN2 is up DHCP.SERVER 172.16.101.0/24 and WLAN2 (AP2) is connected to it

On WLAN2 (AP2) traffic goes through the WAN (aka LAN), how is routing configured correctly for a separate interface? made 1 attempt and got a connection drop.

I connect to WLAN2 (AP2) by phone, but the traffic goes through 217.19.XX (white IP), but I want to achieve it through 62.221.XX (white IP)

Answer 1

But why is the gateway on the phone [phone]
