Hi all, A) I need the Comparison table between ISA server and Other Firewall products. Where can i get it?. B) When we need to establish a VPN connection between two corporate networks(ex Corp I and Corp II) , Is it Compulsory to install the ISA server on both the Side.( Both the Corporate are connected to Internet.thru leased line) Here I have two scenarios, one is two way communication and another is one way communication( I need to access only the Corp I network from Corp II network) So when i need to install the ISa server Both the side? I think it's very silly doubt. i am new to administration and ISA. Sorry for the silly doubt. Thanx in Adv With regards, B.saravanan
