Specific IP data to a specific connection when multiple connections running

Hello everyone

I am going through some trouble, which I cant figure out how to solve.
I have a computer which I have to connect to a VPN through dial-up,
which I havedone pretty easily. But I have to remotely access that same
machine through LAN. The problem is that the machine when connected
simultaneously to the LAN and the dial-up VPN, doesn't send the data to
the VPN and recieve from it like it should, instead I think it directs
the packets to the LAN.

But the good part of the problem (which I think will make it easier to
solve!) is that when I use the dial-up to connect to the VPN, I just
want communicate with a specific IP. I think the problem just boils
down to how to send data directed to a specific IP to a specific
network interface / connection.

Any ideas.
Thanks to anyone who can help me out.

Ahmad

I am not sure I understand the issue. However, if you want to access email or internet go to one router and other go different direction, you may setup IPSec and modify the routing table. this troubleshooting may help,

Routing One router goes to the corporation email server and another one goes to the Internet. Symptoms: you have one router connecting to the corporation for email ...

Okay here is the ipconfig /all. As you can see I have two completely
different adapters giving me to network interfaces. One is an ethernet
adapter connecting to the company's LAN and the other is a modem which
connects to another company's VPN using Dial-up.

----------------------------------------------------
My problem is that any packet destined for the IP - 146.20.1.51 from
this machine should go through the modem (PPP adapter PIA Sabre VPN).
What should I do? Would any netsh command be useful?

Any ideas?
