Multiple site VPN architecture question?

[rhoenisch]

We are currently in the process of planning our move to fiber.  We have a corporate location and 15 remote offices.  I would like to create VPN tunnels from each remote office back to the corporate location. 

Our remote offices mostly use 2811s.  The core at our corporate location is a 3750.  I am wondering if the logical step is to just create IPSEC VPN tunnels from the 2811s to the 3750?  Will this be too taxing on the 3750 to have 15 separate VPN tunnels?  I have a cisco background, but I am fairly new to handling massive architecture changes and adjustements.  Thanks for your help.

Depends.

If u are using 3750 for Internet Access  , DHCP , some qos , ofc NAT ..... i sugest to use other router. I was using for VPN to remote sites Cisco 1921 with SEC license and it worked fine ( not much traffic aprox. 20-30 Mbps )
