I was planning to implement ISA 2006 behind/side-by-side with ASA 500 cisco firewall. Can anybody tell me the recommended way to go with it?
I read somewhere that if our cisco asa is configured correctly then we do not need isa 2006 in firewall mode and can go for isa2006 caching and webproxy mode.
While i got recommendations of isa 2006 edge firewall settings behind cisco ASA 500 firewall.
Right now i have my network like this :
user > isa2000 > Core Switch > Cisco ASA 500 Firewall > > > ISP
Can i Chnage it to
User > ISA 2006 Edge Firewall > COre Switch > Cisco ASA500 > ................ISP
Kindly guide me for this design please.
