- WARNING: Using Registry Editor incorrectly can cause
- serious, system-wide problems that may require you to
- reinstall Windows NT to correct them. Microsoft cannot
- guarantee that any problems resulting from the use of
- Registry Editor can be solved. Use this tool at your own
- risk.
-
- Summary:
-
- This article describes how to enable TCP/IP routing in Windows NT and
- how to configure static routing tables using ROUTE.EXE.
-
- How to Enable TCP/IP Routing
- ============================
-
- Routing between subnets is disabled by default for the TCP/IP protocol
- in Windows NT. To enable routing, following these steps:
-
- 1. Start Registry Editor (REGEDT32.EXE) and go to the following
- subkey:
-
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip
- \Parameters
-
- 2. From the Edit menu, choose Add Value.
-
- 3. Enter the following values:
-
- Value Name: IpEnableRouter
- Data Type: REG_DWORD
- Value: 1
-
- 4. Exit Registry Editor and restart Windows NT.
-
- Configuring Static Routing Tables
- =================================
-
- If two subnets are separated by more than one Windows NT machine or by
- a router, Windows NT can route between the subnets if you manually
- configure the routing tables. Static configurable routing is
- supported, but neither routing information protocol (RIP) or OSPF are
- supported.
-
- The ROUTE.EXE command manually configures network routing tables.
- ROUTE has the following syntax:
-
- route [-fs] [command [destination][gateway]]
-
- Switches
- --------
-
- -f Clears routing tables
-
- -s Packets for which no destinations are found are routed to the
- smart gateway.
-
- Commands
- --------
-
- add Adds a route
- delete Deletes a path
- print Prints a route
- change Changes an existing route
-
- All symbolic names used for gateway and destination are looked up in
- the database files NETWORKS and HOSTS.
