However, you can get failover for Firewall clients by using Round Robin DNS. HTH, Tom Hi Tarek,

The failover feature I discussed only works for Web Proxy clients.

Question # 1 : My Firewall client is auto detecting ISA-1, and the Alternative ISA Server option is pointing to ISA-2 , now IF ISA -1 were shutdown/failed, the users will continue to be able to surf the Internet using ISA-2 ?? ( assuming ISA-1 & ISA-2 have identical rules and settings ) Question # 2 : Now ISA-1 came back online, how can i shift back my users to use ISA-1 ? Question # 3 : Can i have this option as well on ISA-2 ? so that when ISA-2 fails, users will automatically be shifted to ISA-1 ? The Scenario is as follows: ISA-1 have this option pointing to ISA-2 ISA-2 have this option pointing to ISA-1 now ISA-1 failed, users will start using ISA-2, what if ISA-2 failed ? will users be able to automatically go back to ISA-1 ( assuming it went back online before ISA-2 failed ) Thanks, Tarek Hi Tom,

I never tried this !

Question # 1 :

My Firewall client is auto detecting ISA-1, and the Alternative ISA Server option is pointing to ISA-2 , now IF ISA -1 were shutdown/failed, the users will continue to be able to surf the Internet using ISA-2 ?? ( assuming ISA-1 & ISA-2 have identical rules and settings )

Question # 2 :

Now ISA-1 came back online, how can i shift back my users to use ISA-1 ?

Question # 3 :

Can i have this option as well on ISA-2 ? so that when ISA-2 fails, users will automatically be shifted to ISA-1 ?

The Scenario is as follows:

ISA-1 have this option pointing to ISA-2
ISA-2 have this option pointing to ISA-1

now ISA-1 failed, users will start using ISA-2, what if ISA-2 failed ? will users be able to automatically go back to ISA-1 ( assuming it went back online before ISA-2 failed )

Thanks,
Tarek
