[Firehol-support] Firehol 2xISP Failover Config - Please Help

[Andrei Verovski (aka MacGuru)]

Hi, folks,

I have SuSE Linux server which acts as 2-interface router & firewall  
with firehol package for firewalling setup.

Now we would like to add backup net line to another ISP via third net  
interface. so if connection to ISP#1 fail, all traffic will be  
automatically switched to ISP#2. Once ISP#1 becomes available again,  
firewall/router should be switched back.

Anyone have any clue how to do it with firehol ?

Checking net connections probably have to be done via cron script and  
1 min interval.

Thanks in advance for any suggestion(s).
