4.2.8 supports IKEv1 only, and this protocol supports full subnets only.
Or is there an extension for arbitrary address ranges?
The newer IKEv2 supports such address ranges, and our daemon can
actually negotiated them. But:
1) there is currently no way to configure such ranges in ipsec.conf
2) the Linux kernel can handle policies with full subnets only
If a range is negotiated, it gets mapped to the next larger subnet.

It would require major effort to extend the kernel accordingly. So it
probably won't happen soon, unless somebody is willing to sponsor it.
