Cannot use network (not even ping) when using balena-engine #466

Description

I cannot use network, or even ping anything when using balena-engine. If I add --net host it starts working again.

Steps to reproduce the issue:

  1. Just run sudo balena-engine run --rm balenalib/amd64-ubuntu:jammy ping 8.8.8.8

Describe the results you received:

$ sudo balena-engine run --rm balenalib/amd64-ubuntu:jammy ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
^C^C--- 8.8.8.8 ping statistics ---
9 packets transmitted, 0 packets received, 100% packet loss

Describe the results you expected: When using docker, I just get correct output:

$ sudo docker run --rm balenalib/amd64-ubuntu:jammy ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: icmp_seq=0 ttl=56 time=33.608 ms
64 bytes from 8.8.8.8: icmp_seq=1 ttl=56 time=34.124 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=56 time=33.602 ms
^C--- 8.8.8.8 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
