FreeBSD 13에서 bhyve를 사용하여 Ubuntu 21.04를 에뮬레이션할 때 인터넷에 연결할 수 없습니다.

FreeBSD 13에서 bhyve의 네트워크 스택을 아래와 같이 구성했지만 ubuntu VM이 인터넷에 연결할 수 없습니다.

1) on /etc/rc.conf : gateway_enable="YES"
    
2) root@marietto:/home/marietto # sysctl net.inet.ip.forwarding=1
net.inet.ip.forwarding: 1 -> 1

3) root@marietto:/home/marietto # sysctl net.link.tap.up_on_open=1
net.link.tap.up_on_open: 1 -> 1

그런 다음 콘솔에서 다음을 수행합니다.

root@marietto:/home/marietto # kldload vmm

kldload: can't load vmm: module already loaded or in kernel

root@marietto:/home/marietto # ifconfig tap0 create up

root@marietto:/home/marietto # ifconfig bridge0 create up

root@marietto:/home/marietto # ifconfig bridge0 addm em0
ifconfig: BRDGADD em0: File exists

root@marietto:/home/marietto # ifconfig bridge0 addm tap0

root@marietto:/home/marietto/Desktop/Files/Bhyve/bhyve # ifconfig

다음 명령을 사용하여 ubuntu 21.04 VM을 시작합니다.

첨부한 사진에서 볼 수 있듯이 Ubuntu VM은 인터넷에 연결할 수 없습니다. 이유를 이해하도록 도와주실 수 있나요? 우분투에 뭔가 문제가 있다고 확신합니다.
