Gateway require a point to point route

[aspineux]

Hi, her is my problem

On the WAN side, I have only one host, the gateway.
The WAN IP is a public address (I use 10.10.10.11 in my sample below)  with a mask of 32
Other hosts have IPs on the same range 10.10.10.X somewhere else in the ISP networks.
Tthen I cannot use 10.10.10.11/24 for my IP wan because I would lose the possibility to connect to these hosts
at 10.10.10.X !

10.10.10.11/32 WAN  < –--- >  GW (10.10.10.254)  ~~ ISP ~~  GW (10.10.10.254)  < ----- >  10.10.10.X/32
                                                        |
                                                        |
                                                    Internet

Under linux, I use this setup :

first setup the IP of the WAN interface

ifconfig eth0 10.10.10.10 netmask 255.255.255.255

add  a route to the gateway on the eth0 side

route add -host 10.10.10.254 dev eth0

now linux know how to reach 10.10.10.254,

I can use it as a GW

route add default gw 10.10.10.254

And it works

I can I do similar stuff under pfsense using the commands

route add -net 10.10.10.254/32 -iface em0
route add default 10.10.10.254

But how can I do it using the GUI.
