I'm happy to look at outside addresses, just not the ones on the inside.
I would also consider matching up endpoint (VPN gateway or "outside")
address and SPI to know which SA a packet is arriving on, for the
inbound-through-tunnel direction, and then use the vlan interface name
to help select the departing tunnel, if possible.

Well, not perhaps without some nethacks in the kernel.  I've certainly
done that before, but would prefer something more vanilla.

Thanks,
