Description

Hyperkit network is configured in bridged mode and not configured as a NAT mode, which makes an issue with VPN clients which only allow/pass connections from domicile host.
Is it possible to start/configure crc/hyperkit to switch to NAT mode?
The culprit is marked bolded, can not remove it from routing table, and it writes packet to this IP 192.168.64.2, which is dropped by the VPN policy.

Research direction

Start by tracing how Hyperkit configures macOS networking and compare the current bridged setup with the routing table shown in the issue. Done would mean a supported way to use NAT mode so VPN policies accept connections from the host.
