Network Rules
Network rules determine whether there is connectivity between two networks, and what type of connectivity is defined. Networks can be connected as follows:

Network address translation (NAT). With this connection type, ISA Server replaces the IP address of the client on the source network with its own IP address.

Route. With this connection type, client requests from the source network are directly relayed to the destination network. The source client address is included in the request.

For both NAT and route relationships, you can allow traffic by configuring firewall policy rules.
