Initiate IPsec S2S VPN via L2TP IPsec W7 client

Hi

We own a ssg350M that host about 50 IPSEC S2S tunnel. I have setup a L2TP/IPSEC tunnel(policy base VPN) with certificate(W7 client) to the same firewall so the question is the following. Is the Juniper is able to initiate an IPSEC S2S from the L2TP/IPSEC

VPN?
I am a bit stucked all packets belonging to an IPSEC tunnel are dropped IE 10.5.223.0/24 even if i explicitly add Dial-Up VPN policy action tunnel allow any. I keep having "No policy matched for tunnel traffic". Nevertheless the local network if perfectly accessible from L2TP. What i am doing wrong?
Something i wish to add is i connect the L2TP on same interface as the one used for IPSEC S2S is this an issue?

Thanks for reading
