virt-manager VM cannot access outside network when VPN is enabled

I am running CentOS7 as a VM on Virtual Machine Manager (virt-manager 2.2.1) on Ubuntu 20.04.1. On the same Ubuntu machine I am running AnyConnect 4.9.03047 to connect via VPN.

When the VPN is not connected the VM has access to the local network and the internet. But as soon as I connect AnyConnect to the VPN the VM loses connection.

The Virtual Network Interface is configured with the default configuration:
Network source: NAT
Device model: virtio

Is there anything I am missing that would allow network access while VPN is connected?
