Here is how I want the configuration; I have one DSL router and one Cisco 1721 router. My concern is how I can configure VPN through these two routers.
I have attached a picture file called Net Diagram which says my current scenario. And I have added one more picture called router configuration which says my Cisco routers current configuration, please have a look at the both pictures and have a VPN solution for this. I would really appreciate if any could help me in this.
Suggest you asign a public IP and statically nat the vpn server on the DSL router and use that as the IPSec peer in all the client locations or terminate the ipsec in the dsl router(should have a static ip) and let go of your vpn server all together.
