This is a breaking change because env vars were renamed.
Previous versions were using just ingress rules to block traffic.
This release introduces option to use address-list for ingress (src) and egress (dst) rules in the same time.
Env vars renamed:
IP_FIREWALL_RULES -> IP_FIREWALL_RULES_SRC
IPV6_FIREWALL_RULES_SRC -> IPV6_FIREWALL_RULES_SRC
Env vars added:
IP_FIREWALL_RULES_DST
IPV6_FIREWALL_RULES_DST
see readme for more details.
