VPN star topology

Hi,

We have a datacentar with ASA device and couple od branch offices with 1841 routers and one branch office with a 3650 L3 switch. Is it possible to make VPN connections (IPsec) between 1841's and 3650 on one side,  and  ASA on the other, where ASA would be VPN concentrator?

ASA and 1841 should be fine but 3560 will not support VPN.

Re: VPN star topology

I want to establish VPN with GRE over IPsec. As ASA can't end GRE tunnels, I should pass it through inside to another 1841 router in datacentar network. Since datacentar is connected to internet via two wan links (separate ISPs) is it possible to establish two gre simultanous sessions between 1841 at branch office and 1841 at datacentar, one session per wan link at datacentar? That way, I need 8 gre separate sessions (tunnels) at datacentar 1841 router. Is it supported?

Is GRE passthrough works like regular port forwarding or it is something that ASA handles with some special commands?
