Hi,

This is what itojun told me one day...

        kame/openbsd and openbsd-current are a bit different.

        If you use openbsd-current, you need to perform
        # sysctl -w net.inet.ip4.allow=1
        to allow incoming tunnelled packet to use gif interface.

But as you are using KAME's kernel, this is probably not the point, unless they
have now merged that far ... (but, as you said, you don't see
net.inet.ip4.allow with sysctl)
