Configuring a routed connection

Configuring a routed connection
To configure a routed connection to the Internet for a small office or home office (SOHO) network, the following are configured:
The server running Routing and Remote Access.
Other computers on the SOHO network.
Configuring the server running Routing and Remote Access to act as a router
To configure the server running Routing and Remote Access to act as a router, the following steps are completed:
The TCP/IP protocol on the server running Routing and Remote Access for the SOHO network interface is configured with:
IP address (from the address range obtained from the ISP).
Subnet mask (from the address range obtained from the ISP).
DNS server (from the IP address received from the ISP).
TCP/IP is configured through the properties of the TCP/IP protocol for the local area connection in Network Connections.
Note
- Do not configure a default gateway.
The Routing and Remote Access service is installed and enabled.
For information on installing and enabling the Routing and Remote Access service, see Enable the Routing and Remote Access service.
Routing on the dial-up port is enabled.
If the connection to the Internet is a permanent connection that appears as a LAN interface (such as DDS, T-Carrier, Frame Relay, permanent ISDN, xDSL, or cable modem), or if you are connecting your server running Routing and Remote Access to another router before the connection to the Internet, skip to step 5.
For information about enabling routing on the dial-up port, see Enable routing on ports.
A demand-dial interface is created to connect to the ISP.
A demand-dial interface is created that is enabled for IP routing and uses the dial-up equipment and credentials that are used to dial the ISP. For more information about creating demand-dial interfaces, see Add a demand-dial interface.
A default static route is created that uses the Internet interface.
For a default static route, the demand-dial interface (for dial-up connections) or LAN interface (for permanent or intermediate router connections) that is used to connect to the Internet is selected. The destination is 0.0.0.0 and the network mask is 0.0.0.0. For a demand-dial interface, the gateway IP address is not configurable. For a LAN interface that is a point-to-point connection to your ISP, the gateway address is 0.0.0.0.
For more information about configuring a default static route, see Add a default static IP route.
Multicast support is configured (optional).
To add multicast support to the SOHO network:
The IGMP routing protocol is added. For more information, see Add the IGMP routing protocol.
IGMP router mode is enabled on the interface that is connected to the home network. For more information, see Enable IGMP router and IGMP proxy mode.
IGMP proxy mode is enabled on the interface that is connected to the ISP. For more information, see Enable IGMP router and IGMP proxy mode.
Configuring other computers on the SOHO network
The TCP/IP protocol on the SOHO hosts is configured with:
IP address (from the address range obtained from the ISP).
Subnet mask (from the address range obtained from the ISP).
Default gateway (the IP address assigned to the SOHO server running Routing and Remote Access network adapter).
DNS server (from the IP address received from the ISP).
TCP/IP is configured through the properties of the TCP/IP protocol for the local area connection in Network Connections.
Notes
The previous configuration of SOHO hosts assumes that TCP/IP is configured manually. To automatically configure TCP/IP for SOHO hosts, you must install and configure a DHCP server. For more information, see DHCP Overview.
