Configuring Services and ICMP Messages

The next step in setting up NAT (or a firewall) on an interface is to specify the services that are allowed in. For example, if there is an FTP server on the internal network and you want external users to be able to access it, you need to enable FTP. In the RRAS console, click NAT/Basic Firewall and then open the properties for the network interface in question. Click the Services and Ports tab (see Figure 18-9).
