Add reverse-route under your dynamic map config
crypto dynamic-map dynmap 10
set transform-set myset
reverse-route
This will inject a route into the routing table which will point to the other side of the tunnel. If you want to use split tunneling you'll need to add an acl with the subnet you want to allow access and add it to your group vpn config. without split tunneling your remote host will route all traffic through the vpn tunnel.
I hope this helps
