FDM Dual ISP Failover

[jaydee201]

Hi Guys,

I have a Cisco 1010 FTD using FW version 7.2.4 and I have 2 ISPs. One is a leased line but the other is a FTTC so that uses a PPPoE username, password with 1 singular external IP address. I have found the solution of an SLA monitor the default routes so that if the main one drops the secondary will take over but with the FTTC line there isn't a static external IP that is used for the gateway and it is a dynamic gateway so I can't set up the SLA monitor on a dynamic IP. Is there any way this can be done managed via either FDM or FMC. The firewall is currently being managed locally via FDM.

Any advice would be greatly appreciated.

I have come across this article before and it would work great if both of the ISPs had a static IP address for the gateway but when I go to add the backup ISP in, there is no static gateway IP and the gateway address can change on this line, so therefore this method won't work because you have to define the gateway IP on the SLA which we cannot do.

Did you find a solution on that or it cannot be done?
