To set up this network, follow these procedures:
Set up MS Proxy Server 2.0 and make sure you can access the Internet (or external network) from that machine. On the Proxy Server, make sure that "Enable IP Forwarding" is enabled for the TCP/IP protocol.
On the TelnetServer, install the MS Proxy 2.0 Client. Make sure you can access outside to the Internet (or external network) through the Proxy Server from that machine.
NOTE: For more information on the installation and configuration of MS Proxy Server and Clients, please see the documentation that accompanies that product
On the Proxy Server:
Go to the IIS Manager (Start\Programs\MS Proxy Server\Internet Service Manager).
Select the Winsock Proxy Service and double-click to bring up its properties.
Select the Protocols tab and click Add.
In the Protocol Name field type "Inetdsrv". For the initial connection, type in port "23". Select "TCP", and "Inbound" for the direction.
Click Add&ldots;
For the Port Range Definition for subsequent connections, type "23" in the first box and leave the second box blank. Select "TCP" and "Inbound" for the direction.
Click OK three times to exit back to the Internet Service Manager.
On the TelnetServer:
Create a wspcfg.ini file in the same directory where inetdsrv.exe is installed (\InterAccess\InetD) This file should have the following entries:
[Inetdsrv]
ServerBindTcpPorts=23
KillOldSession=1
Persistent=1
From a command prompt, change directories to the location where the MS Proxy Client was installed (\mspclnt).
Use the CREDTOOL utility to assign the TelnetServer administrator privileges on the Proxy Server. From the command line, type:
CREDTOOL –w –n inetdsrv –c userid domain password
Be sure to use a userid that has administrator privileges for the Proxy Server
NOTE: If the CREDTOOL utility is not located in the \mspclnt directory, you can copy the program (credtool.exe) from the MS Proxy CD-ROM.
Now, reboot the Proxy Server. When that is done, reboot the TelnetServer. Stop and restart the Winsock Proxy Service on the Proxy Server (in Internet Service Manager). Stop and Restart the InetD service on the TelnetServer. From a command prompt:
NET STOP INETD
NET START INETD
This will allow external Telnet Clients to connect via the Proxy Server. Connecting to the IP address of the external NIC of the Proxy Server will connect to the TelnetServer located on the internal network. The Proxy Server will forward the requests of the Telnet Client to the TelnetServer
If all of the above does not work for you, also try reinstalling the Proxy Client on the TelnetServer.
