I'm trying to connect to a Cisco VPN using an USB-tethered connection using OpenVPN. The moment I enable Cisco AnyConnect, traffic stops on OpenVPN interface, resulting in disconnection.
OS is Windows 7 64-bit.
I believe AnyConnect will change the default gateway, so all traffic goes through it (i.e., the default behavior is not to do split routing). In that case, you may no longer be able to reach your OpenVPN server if the AnyConnect destination disallows that traffic.
