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

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
DLLs and images are upgraded from the Service Pack.
