The target VPN server I want to connect to allows connections only from one IP address.
When I am at my office (the network public IP is trusted on the VPN server) everything is OK, but I figured that when I am at home I could do the following:
Connect to office VPN (using built in windows VPN client)
When I do it I have 2 active network interfaces:
- home network
- office network (VPN)
Connect to target VPN (using custom VPN client)
If the VPN server sees my office IP, it should let me in.
Unfortunately, I get rejected. The strange thing is, I made it work this way:
I connect to VPN at my office
I start a bridged virtual machine
I connect to target VPN in the virtual machine
and it works.
Probably, all virtual machine traffic is routed through the office VPN connection.
My question is, how can I make it work without the virtual machine?
