Backup route with single WAN box?

fw_bob

Hi everyone,
I have a simple fw running pfsense (LinITX APU 1D)
It has 3 NICs - one WAN, one LAN, one OPT1

The WLAN is connected to a FTTH services using PPOE. However this sometimes fails and for those rare occasions I would like to use my BT ADSL service that I still have available.

Is there anyway I can use a static route or similar to route to the BT ADSL if the WAN is down?

eg;

FTT======-WAN pfsense -----------LAN--------BT ADSL Home
          192.168.1.1.......................192.168.1.2
                         192.168.1.0/24

Is there anyway to get the pfsense route to 192.168.1.2 if the WAN is down?

Hello there! Yes you can do it as easy as configuring a few settings as described in the following link here you go

Get back to here if you couldn't get it working.

Good luck

I had seen those config options, but they all refer to 2 WANs.

Can I do this with 1 WAN and 1 LAN though?

LeCygne

Sure. Just add the gateway and choose the correct interface and there you go. When creating a gateway group you are free to choose any interface. For instance LAN interface. Thus you can choose WAN1 and a gateway which uses LAN as its outgoing interface. That being said it would be better if you connect both of your Internet-connected devices to the pfsense box.

Are you using the OPT1 interface, if not use that you can rename it WAN2 or ADSL in the interfaces assignment page.

You will have to setup PFsense for a dual WAN or configure a 2nd gateway on your workstations and edit your metric there.

@nogbadthebad interesting. I can free up OPT1 and then make it WAN2 then follow the other suggestions for groups.
Excellent. I will give that a try.
Thanks

And that is exactly what I did. Easy and it works!!
Thanks to everyone for your help and support
