Dear Joseph Thanks for reply.I want to know whether if for a specific Server be it windows2000 server ,in order for this server to be NATed ,do I need to install SecureNAT to do the NATing of this server? Also How can you compare the rule in Checkpoint wherein there is a facility in source node ,destination node as well as protocol to define in one shoy.And I think this facility is not available in ISA. Pls advice. Regards BALA "Joseph G.

Client set and destination set are very much different from each other?.though both are being used in creating different rules applicable to different set of clients. Hence, it helps an administrator to easily control access to his ISA box. CLIENT SET ? Are basically IP Addresses of client computers in your local network (can be a single IP or a group of IP depending on how you want to group them) that will let you apply different access rules (i.e. granting or denying internet access). DESTINATION SET ? From the word itself, ?destination?: can be a list of websites or external IP address/es or even path that lets you apply rules (i.e. blocking access to particular websites). SecureNAT ? is an extensible NAT architecture implemented by ISA to provide secure connection for clients that doesn?t have or doesn?t use the firewall software, like MAC or Unix/Linux clients and other non-Microsoft OS where you can?t install the firewall client software. Hope I defined it clear enough?.

What is the difference between clent set and destination set? For me both sounds same . Also in checkpoint I use to NAT a ip addresses by giving the public Ip address of it into a node ,whereas I could not find anything of that sort in ISA .Also what is SecureNAT .Has it antthing to do with NAT? I request you to assist me in knowing these . Regards C.Piyush --------------------------------- Do you Yahoo!? Yahoo!
