When I create a container with an IPv6 address it behaves really weirdly.
The address is not accessible from the outside.
However, as soon as I ping the address from the VyOS it responds and then becomes also available from the outside.
When I stop pinging the container, it stays available for a couple of seconds and then becomes unresponsive again.
show ipv6 neighbors show it as FAILED and changes to REACHABLE while I ping the container.
When I stop the ping it goes back to FAILED after some seconds.
Does anyone have an idea what the issue could be?
Container config:
name nginx {
image nginx:stable
network homelab {
address 172.18.10.10
address fd9e:63ac:6dcd::10
}
restart always
volume data {
destination /etc/nginx/conf.d
source /config/docker/nginx/data
}
}
network homelab {
description "Docker Network"
prefix 172.18.10.0/24
prefix fd9e:63ac:6dcd::/48
}
(fd9e:63ac:6dcd::/48 placeholder for public IPv6 prefix)
