./30
BG-20–------->PFSENSE BOX------------------------->LAN IP
192.168.2.17/30 PFsense WANIP=192.168.2.18/30 192.168.3.234/29
PFsense LANIP=192.168.3.233/29

Internet is fine with this setup

What I really want here is that I can access my pfsense box either using my pfsense WANIP or LANIP but it seems doesnt work
And also when i try to visit whatsmyip using lan ip addresses it shows the Serial link address of my BG20.

What I want to get is similar to this (cisco routing)

FIRST INTERFACE TO BG20
int fa0/0
ip add 192.168.2.18 255.255.255.252
no shut
SECOND INTERFACE TO LAN
int fa0/1
ip add 192.168.3.233 255.255.255.248
no shut
IP ROUTE**
ip route 0.0.0.0 0.0.0.0 192.168.2.17
