How to set up correct Pfsense routing?

Question

Network administration

There are several white IP addresses on the same network.
A router based on Pfsense 2.1.5 is connected to one of the addresses, it is connected, as usual, with one interface to the LAN, and the other to the WAN.
The problem is that when accessing hosts from the WAN network from the LAN (our white addresses that fall into the same external subnet mask as pfsense), the packets are sent to the provider's gateway.
It turns out this scheme:
LAN -> WAN (psense) -> provider gateway -> White IP from the same network with Pfsense.
I would like to access my addresses directly:
LAN -> WAN (psense) -> White IP from the same network as Pfsense.
How to do it?
Details:
External network: 213.110.xxx.yyy/25 Gateway 213.110.xxx.1
Internal network: 192.168.1.0/24 Gateway 192.168.1.1
pfsense WAN 213.110.xxx.31
pfsense LAN 192.168.1.1
when accessing, for example, the address: 213.110.xxx.32, the following happens:
192.168.1.z -> pfsense LAN 192.168.1.1 -> pfsense WAN 213.110.xxx.31 -> Gateway 213.110.xxx.1 -> 213.110.xxx.32
Should I mention that all other services are working fine!?
