Use Cisco 2821 with SSL2VPN Module as a VPN Concentrator

I have a 10 Mb Fibre connection coming into our office… It is connected to a 2821 ISR that is doing NAT, etc… I have had issues in the past getting site to site VPN’s working on it… The company recently purchased another 2821 with the SSLVPN module in it. I am wondering if I can set this router up strictly for VPN and remote access to offload VPN the primary router. I want to give the VPN Router one of my public IP’s and route all VPN traffic from the main router to the VPN router. I think this will work but was wondering if anyone has done this in the past and could provide some sample configs. Any other suggestions would be appreciated. Thanks in advance.
