Hi,
This is the first time I am setting up a VPN and also fairly new at working on live networks. So, please pardon my ignorance if this sounds like a fairly simple question.
We are trying to set a remote access VPN. We decided to put the VPN 3005 concentrator behind the edge router and in parallel with the core router. I am thinking how do we take care of routing issues.
A VPN client is assigned an IP address from the pool of addresses fed in the concentrator (Lets say we are in the 160.10.X.X domain and I have assigned 160.10.20.1 - 160.10.20.229 for VPN clients). Now a VPN client sends a packet to the concentrator with an IP address of 160.10.20.5. How does the packet get rputed properly. If it gets to the destination how does the edge router know where to send the packet while on its way back. I am thining the edge would think that the IP belongs inside its network and try to forward it there. Can we solve this using static routes. But still the routers in the IP cloud would not be able to forward it correctly.
I am not sure of I am missing some concept or just thinking wrong. Any help/explanation will be greatly appreciated.
Thanks.
