Dual WAN Failover using WISP

[markbarton]

Hi,

Hopefully someone can help - living out in the sticks I have recently got a WISP (Fixed wireless broadband) - which uses a Combo Dish / Radio / Router - I have no access to the router at all thats on the dish. Its sits at 192.168.1.1 on the LAN and has a DHCP server running from 191.168.1.101 to 200. Its plugged into my network via a switch.

My Billion router is currently acting as a Wireless Access Point - nothing else. I have configured it on the LAN at 192.168.1.254 (probably need to change this) - I have an Ethernet cable currently coming into the router via 1 of the inbuilt LAN ports.

This all works but what I want to do is actually use my backup ADSL line in combination with the WISP connection so the ADSL acts as a failover for the WISP connection - so I want to make use of the Dual WAN ports on the router.

The ADSL settings I am fine with - what I a not sure is how to configure the WISP connection. I don't want the router to do anything other than fail over to the ADSL line - no DHCP / firewall etc as I think it would just interfere with the WISP router when it comes back up.

Looking at the WAN service interface I am not sure which type to use - Bridging maybe?

Thanks

Mark

The only option is configure the device for EWAN/Ethernet mode (plug your WISP into the EWAN port), 'Type = IP over ethernet' so it obtains a IP address from your WISP router, but then the 7800DXL will have to primary router, otherwise the failover won't work. DHCP will have to be on, if off you will have to set static IP's to each device so you can have internet access once failover has kicked in and running on ADSL mode

If you make the 7800DXL run as a access point only then it won't failover to ADSL unless the 7800DXL is setup to be primary router (all DHCP request, traffic routing etc will be done via the Bipac 7800DXL)

Ok thanks for that.

I will just have to be careful what range to use for the DHCP - hopefully they wont conflict too much.

Yes maybe use 10.0.0.1 for the Bipac 7800DXL and DHCP range of 10.0.0.100 ~ 10.0.0.199
