VPN to remote network on same subnet as local network

Symptoms: 
You need to connect using VPN connection to remote client site and realize that you both using same IP subnet. You connect fine but can't access any resources on the remote subnet. Some people may suggest you to change one of the subnet, but you can't do that because both of subnet are office environment.


Cause:
It's network and route thing. Your PC think the remote IP is locally.


Solution:
You need to manually add routing for remote IP at your PC. You can do that using command ROUTE.
1. Connect to VPN site.


2. From command prompt run ROUTE PRINT to show status. In my case:

3. From here, we get information:

   - 10.10.10.9      my current IP

   - 10.10.10.79     my assigned VPN IP

   - 0x60004               my VPN interface

   - 2xx.2xx.2xx.2xx  I need to hide my client public IP

4. To manually add route run:

ROUTE ADD <TargetIP> MASK <Mask> <GatewayIP> METRIC <Metric> IF <InterfaceID>

so for my case if I want to add route to single IP 10.10.10.18 on remote site:

ROUTE ADD 10.10.10.18 MASK 255.255.255.255 10.10.10.79 METRIC 1 IF 0x6004

5. Run ROUTE PRINT again to make sure the new route listed

Find Old Network Card not show under Device Manager

Symptoms: 

Popup error while setting IP

The IP address XXX.XXX.XXX.XXX you have entered for this network adapter is already assigned to another adapter Name of adapter. Name of adapter is hidden from the network and Dial-up Connections folder because it is not physically in the computer or is a legacy adapter that is not working. If the same address is assigned to both adapters and they become active, only one of them will use this address. This may result in incorrect system configuration. Do you want to enter a different IP address for this adapter in the list of IP addresses in the advanced dialog box?
