virtualbox.org

I have searched and failedto find anything that enabled me to resolve this.

Scenario:-

Host. Windows 7. Guest Windows 2000.

On the host I have a wireless card and a (disabled) network adapter. I also have configured a loopback adapter (for networking to the guest). This has an IP address of 192.168.144.61.

The host has a network adapter bridged to the loopback adapter and an address of 192.168.144.217.

I am able to ping both host and guest from each other - when the VPN is not active.

However the VPN is a CISCO VPN and IPASS is in use. When the VPN is connected the situation changes. The guest can still ping the host. However the host cannot ping the guest.

I am unsure as to how and try to resolve this, I have searched various areas and found lots of useful information, but still haven't been able to find a way to solve this.

Any help would be much appreciated.

Thank you.

Most likely your VPN is configured to forward all kind of traffic via its connection (no split-tunneling) and/or the VPN actually set a route to that specific subnet in your routing table. You can check your routing table after being connected to the VPN using Either way, this is not a Virtualbox problem but a Cisco client issue and you should take support to them or to your network administrator.

Thanks, that is what I was suspecting. I was just hoping that maybe somebody had a similar issue and had found some sort of solution.

There isn't a real solution to this I am afraid. The only way would be to enable some kind of "split tunneling" option in the Cisco client, but it could be controlled via policy on the server side aswell.
In any case, it all depends how everything is configured.
