Subjet: 2 LAN Cards in one(1) PC

I have windows 2003 server( static ip assign by router - LANCARD1) with 2 lancards on it.. the one connected to router with internet connection(router's gateway ip: but the other one connected to modem( - gateway - LANCARD2) which is another private line(VPN) connected to other branch company, another modem there(branch modem IP: if one cable connected to LANCARD2 there's a response when I ping it..but i manually assign IP to LANCard 2(; subnet:; default gateway: which is connected to Modem( - gateway)

Poblem: but if when plug-in 2 LANCARDS the lancard1 which is connected to router with internet.. has no signal or time out.. but when i unplug the cable from lancard2(connected to VPN) and there's a signal.. could help me to solve this problem???


1 PC - Installed Windows 2003 Server with 2 LANCARDS on it.
LANCARD1 - – connected to ROUTER with internet (static IP assign by router)
LANCARD2 - - connected to MODEM1 without internet which is connected another private line link to another branch and there’s also a MODEM2 there..

ROUTER’s GATEWAY IP: - Office router with internet connection

MODEM1 – Gateway IP -- Office - New Line, connected to another Branch
MODEM2 – Gateway IP ---- Branch - New Line, connected to Office

MODEM1 & MODEM2 are connected each other.. - NEW LINE

LANCARD1 configuration – Static IP assigned by ROUTER IP address:
Subnet Mask:
Default Gateway:

LANCARD2 configuration - Manually assign IP: - New installed LAN CARD
IP address:
Subnet Mask:
Default Gateway:


When I plug the cable to LANCARD2 then I ping MODEM2 ---- there’s a response..
C:\Users\Rogen d>ping –t

But when I plug the both cable to LANCARD1 and LANCARD2 respectively;
The LANCARD1 has no connection...
C:\Users\Rogen d>ping –t time out

Question: How do I configure both LANCARDS so that they can work properly together
and also i can ping MODEM1, MODEM2, LANCARD1, LANCARD2 & ROUTER?

And how to use ROUTE command, if this is a solution.. ?

And lastly what do we call this type of networking?? is this VPN, EXTRANET, INTRANET? could u explain to me.. ?

Thanks so much for your time and effort...

There are a couple of problems. Windows isn't the best with multiple NICs & VPNs don't allow split tunneling. A dual WAN router might be the answer.

I don't have a brand to recommend. That's your decision.
