The subnet-to-subnet eroute should cover this ping; if klips is searching for
a gw->subnet eroute when you ping from subnet-to-subnet, then I'd predict the
packet is being rewritten before the ipsec interface sees it. What NAT rules
are you using?

Make sure that packets destined for 10.0.0.0/8 are exempt from masquerading.
