The port range must map to a port mask, though since the kernel does not
support arbitrary ranges.
+- The vici plugin allows the configuration of IPv4 and IPv6 address ranges
+ in local and remote traffic selectors. Since both the Linux kernel and
+ iptables cannot handle arbitrary ranges, address ranges are mapped to the next
+ larger CIDR subnet by the kernel-netlink and updown plugins, respectively.
+
+- Implemented IKEv1 IPv4/IPv6 address subnet and range identities that can be
+ used as owners of shared secrets.
