Use the NetManage Chameleon version 4.01 or later.
Edit the slip.ini file and confirm that the PPP script contains the
Confirm that the PPP client configuration is correct, and that the
defaults are valid. The router and gateway entries should be all zero.
Double-check your IP address (if dynamic allocation, this should be
0.0.0.0). The subnet mask should be the default for your IP address
(if dynamic, this will be given during PPP negotiations).
Verify that the login name, password, and domain name are all correct.
If your machine is not physically connected to a network, make sure that
the MS Loopback Adapter is installed. (That is, if you are using RAS as
your only network connection.) After adding the MS Loopback Adapter,
the network bindings will be reconfigured. You will be asked for TCP/IP
settings for the adapter. Enter your IP address and subnet mask.
Leave the default gateway clear.
Be sure that the Remote Access Service is installed. Select enable
receiving calls. Select Control panel, then Remote Access Service, then
Configure, then Network Settings enable TCP/IP in the middle section.
Configure this and allow access to the entire network (this may not be

Using the Registry Editor, set "IPEnableRouter" (REG_DWORD) to 0x1
in order to enable IP routing.

If other clients on the local subnet will be using the NT RAS
server as a router, you should also set the following:
You may need to add the registry key entry "DisableOtherSrcPackets".
Set "DisableOtherSrcPackets" (REG_DWORD) to 0x0 to enable the IP packets
from the other clients on the local ethernet to pass through the
NT gateway. You can also set it to 0x1 to disable other clients IP
