hi..
PART 1
current setup pfsense configured like below
ISP-->FibreCable-->RJ45 Fiber Optic Media-->pfsense box

pfsense box is having 2 nic one WAN and other LAN

so everything is running fine.

PART 2
Now i have got one Broadband connection for which ISP provided Router(Zyxel P-660HN-T1A) with 1 static IP configured.

System Mode=Routing

So the real question is how do i configure this Broadband connection on pfsense ? Since I am going to diconnect my FibreOptic connection

What i have tried till now?
got the manual of router. gone through it


changed System Mode=Bridge Mode and configured the IP on pfsense box(wan NIC) after this i though it will start working...but it didn,t

What more i have to do to get it working?

gone through one of this link http://whirlpool.net.au/wiki/adsl_mo...er_bridge_mode

If the router the gave you acts as dhcp seve it will issue an ip on a private subnet.

This will be blocked from wan usage because wan is not normally considered to have a private network ip. You will have to change the options on the interface web configurator to allow private ip adreeses, cannot remember exactly what it was called but it is a check box to uncheck under block bogon networks.
