Configuring Hosts for Enhanced Proxy ARP

To communicate directly over a LAN environment using enhanced proxy ARP, you must configure hosts to ARP for all destination addresses. The following topics describe how to configure common operating systems for ARP routing.

Configuring Windows NT Hosts

Procedure:

Step Action
1 Log in as the administrator.
2 From the Control Panel, select the Network icon.
3 Choose TCP/IP network from the list box and click Configure.

5 Click OK . The configuration is complete.

 

Configuring Windows 95 Hosts

Procedure:

5 Click OK. The configuration is complete.

 

Configuring DIGITAL UNIX and LINUX Hosts

To configure DIGITAL UNIX and LINUX hosts, modify the /etc/routes file and add the following entry where n is the IP address of the host.

Example:

/etc/route add default n.n.n.n 0

 

Configuring MIPS ULTRIX Hosts

To configure MIPS ULTRIX hosts, use the /etc/route program to add a default route into the routing table (insert the line in /etc/rc.local to ensure it is executed at startup) where n is the IP address.

Example:

/etc/route add default n.n.n.n 0

 

Configuring Windows 3.1 PATHWORKS Hosts

Procedure:

Step Action
1 Edit the cfg*.tpl file currently being used. To determine the correct cfg file, access the pathworks directory and open the select.ini file.
2 In the cfg*.tpl file, replace "TCPIPGATEWAY=" with 0.0.0.0.
3 Save the file and restart the system.

 

Configuring Windows NT 4.0 DHCP Servers

The DHCP server, NT 4.0 Service Pack 2, supports configuring hosts with their own address as the default gateway. To enable this feature for all clients in a scope, add the following value to the registry, where n.n.n.n is the subnet for the scope.

HKEY_LOCAL_MACHINE\

    SYSTEM\

        CurrentControlSet\

            Services\

                DHCPServer\

                    Configuration\

                        Subnets\

                            n.n.n.n\

                                SwitchedNetworkFlag=1

                (REG_DWORD)

Note:  Enable the DHCP server function before you install the NT Service Pack 2 to ensure that the DHCP server DLL’s and images are upgraded from the Service Pack.
