sorry if you felt offended. i really think it is issue in routing
table, as multiple SPD configuration works just fine here.
the "unknown/unsupported protocol" error can be increased by multiple
reasons, including decryption resulted into garbage. so it can mean
almost nothing. it can be because of different key setups in SAD,
or whatever.
even if you don't think related, we need your exact configuration
to repeat, or emulate your setup. i have tested a configuration
that should emulate your setup, but it worked. so i guess we need
to emulate whatever you have configured, put some debugging printfs,
to chase what is going on in the kernel. of course we need to
get some equipments to do that, and it takes time.
i understand your frustration, really feeling sorry about it.
ipset setup is really a f*cking complex beast, because of the
specification itself, and because of the interaction of
multiple other network components. we need to know everything
about your setup to repeat the symptom. also, there are a lot of
wacky interaction in FreeBSD IPv4 code path, which makes it really hard
to track the problem down. if you have any other setups including NAT,
divert socket, packet filtering (ipf/ipfilter), routing, ifconfig,
special servers, bridging, whatever, please show them to us.
otherwise we can never repeat that setup.
even if you know that "additional SPD entry tickles some problem"
in your environment, that may not be the real reason.
i believe this is not the real reason, as multiple SPD entry works
fine here (and other places). so i'm trying to understand what
differentiates your setup and my setup.
so, please send us every configuration you have. preferably
not the meta-script like "${ipaddr-c}". we need what you have
configured exactly.
