./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
