Strongswan don't support port ranges in left/rightprotoport
A support of port ranges in ipsec.conf parameters left/rightprotoport is very helpful to split udp applications on different SAs if the peer has only one IP Address.

charon can handle port ranges internally for IKEv2. However, the Linux kernel does not (and probably never will) support port ranges. While extending our configuration backend would be trivial, it wouldn't be of any use.

Starting with 5.1.0, port ranges can be configured for left/rightsubnet selectors, refer to ipsec.conf(5) for details.
However, none of our kernel backends support such ranges. As it is unlikely that such an extension will be accepted by the Linux networking folks, we can't do much about it.
