Two VPNs in the same time disconnect

[slawek371]

Hello,
Is there any way to connect one VPN using Cisco AnyConnect and another one using Network Connect for second VPN.
In my office we need to connect only through one Network Connect VPN because we use local network and don't need second one to have access to our tools and it works.

At home we need to connect first to AnyConnect VPN and then to another one by Network Connect but then one of these VPNs get disconnected so we can't have access to our tools.

I have read that it happens because there is confilict with IP addresses and it can be solved by vpn tunelling but i havent found any instrucion how to do that. Do you have any idea how it can be done? I am using Windows 7 but some other people Windows 10.

You can't run two VPN clients on the same machine at the same time - usually because (like Cisco Anyconnect) they add a virtual adaptor.

What you can do is use one machine as the first VPN in a sort of router mode, then run the second VPN on your laptop using the first as a gateway.

What does your office IT department say?

Different clients may not play ball in a windows environment but it's certainly possible and common place to use tunnel-in-tunnel VPN's.

Surely this can be achieved using a VM to run a machine in a machine?
For example: I’ve got an Ubuntu machine which runs a Wireguard VPN to connect to my cloud instance.

My wife, for university needed to run some Windows software so I installed Virtual Box and put a Windows 7 guest machine inside, onto which she could install various applications.

She then installed the Cisco Anyconnect software in the guest VM so that she could access the University’s VPN servers.

The ‘inner’ guest machine presumably just sees the network connect presented to it, and is unaware that the host is already using a VPN.

Would this work for you OP?

This would be the easiest was to achieve the goal if you are able to run a VM.

Otherwise, I'd consider looking at running a cross vendor compatible VPN client like openvpn to manage the connections. Although you may need help from someone who knows how to configure this scenario.

You certainly can, I do frequently.

One of my clients (customer) uses Cisco the other Checkpoint, I can connect to both at the same time.

OK, you can in some cases but most companies will set policies which make it impossible or very difficult if you don't know how to work around it. The OP does not sound like a network engineer. If you work for pharma, just as an example, try even installing a second vpn client on your laptop let alone running it.
