Accessing modem interface from LAN

[billy85]

My configuration is the following:
I have pfsense installed on a machine with two Nics, one for LAN with 192.168.1.1/24 as adress, and the second for WAN with 192.168.2.50 as address since this interface has static ip address and is connected to the adsl modem interface which all are in the 192.168.2.1/24 network.
My modem comes with web configuration page accessible on private IP addresses : 192.168.2.1
I want my pc belonging to the Lan network (192.168.1.1/24)  behind the Lan interface of pfsense to access the modem configuration page which is connected to the WAN interface (192.168.2.1) of pfsense.
