The container does not have access outside the container network if the container network is defined.
How to reproduce
Download any container image with shell
```
add container image docker.io/gotechnies/alpine-ssh:helm-chart
configure
set container name alpine image 'docker.io/gotechnies/alpine-ssh:helm-chart'
set container name alpine network alpine
set container network alpine prefix '192.168.0.0/24'
commit
```
Test connectivity
```
vyos@vyos:~$ sudo podman exec -ti alpine /bin/sh
/ # ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
^C
--- 8.8.8.8 ping statistics ---
2 packets transmitted, 0 packets received, 100% packet loss
```
The same config works in rolling release
Source NAT helps in this situation. But the behavior should be the same.
