Planning for a routed connection

While offering maximum flexibility in the types of traffic that can be sent and received, a routed connection requires more configuration. The server running Routing and Remote Access must be manually configured with an IP address configuration and, if DHCP is not being used, all the SOHO hosts must also be manually configured with an IP address configuration. If DHCP is being used, a DHCP server on the SOHO network must be configured with the proper scope and scope options. For more information about DHCP, see DHCP

For this scenario, an Internet service provider (ISP) supplies a range of IP addresses to use for the SOHO hosts and the IP address of a DNS server for host name resolution.

Routing protocols are not needed to propagate IP routing information on the SOHO network. The computers on the SOHO network are either manually configured with the default gateway IP address of the server running Routing and Remote Access or receive a default gateway IP address through DHCP. The server running Routing and Remote Access is not configured with a default gateway but with a default route. For an example of adding the default route on the server running Routing and Remote Access, see Add a default static IP route.

If the ISP is on the MBone, the multicast backbone of the Internet, it can forward IP multicast traffic from the Internet. To receive the multicast traffic, the interfaces on the server running Routing and Remote Access are configured for the IGMP router mode and IGMP proxy mode. For more information, see Configuring a routed connection.

A routed connection to the Internet means that communication can occur with any host on the Internet. It also means that the SOHO hosts are exposed to attackers on the Internet. To provide security, packet filters are configured on the server running Routing and Remote Access to prevent unwanted Internet traffic on the SOHO network. For more information, see Packet filtering.

Computers on the home network are configured to use any services provided by an ISP, such as Network News Transfer Protocol (NNTP) servers and mail servers.
