Routing between NIC & serial on same PC

[Ravi Kiran]

Hi

In our test setup, we have local dial-in server (say
Terminal / PC 1) and a dial-up clients (say Dialing PC/ PC
2). When we dialup (PPP mode) to a server It will assign
me a pre-defined IP. Dial-up clients are connected to our
LAN. Now we need to send data received from PC 1 to
internet thru PC 2, what all we need to setup at PC 2 ? (
NAT + Router ? ). how can we make this work when locally
allocated IPs are used to send Packets.

Connection between PC1 & PC2 is throuch nullmodem Cabel

PC2 would need to have an Internet interface, the Routing functionality
enabled and NAT ( if you are using a private IP scheme for your local LAN )

In order to enable Routing you need to set the following RegKey:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPEnab
leRouter = 0x01

In order to NAT packets, you need to either enable Internet Connection
Sharing, or use Routing & Remote Access.
note that both of these will enable the routing functionality as well.
