+# Before:
+#   Protocols tcp, udp and icmp allowed. When using udp it did not work
+#   Only ipv4 custom timeout rules
+# Now:
+#   Valid protocols are only tcp or udp.
+#   Extend functionality to ipv6 and move ipv4 custom rules to new node:
+#       set system conntrack timeout custom [ipv4 | ipv6] rule <rule> ...
