This is being worked on here by Engineering. If you can file a ticket with Support we can send you a patch when it is available.
You can use 0.0.0.0/32 instead on both sides. I've used that successfully with the Shrewsoft VPN client to pass all traffic from a client through a VPN.
Thanks for workaround, but unfortunately in not so nice and easy in heterogeneous environment with more then 300 s2s vpn
