Greetings,
I am requesting assistance from the engineering community implementing a VPN solution within my business environment. I have attached the topology for your review. Essentially what I am trying to implement is a secure VPN solution using cryptographic encryption (AES 256) with (2) 3945 Cisco routers over a DHCP enabled ISP. These routers have a licensed securityK9 configuration.
Router1/Router2
Username (username) password secret 5 (password)
!
Crypto isakmp policy 1
Encryption aes256
Authentication pre-share
Group 2
Lifetime 480
!
Crypto isakmp client configuration
Key secret password
Domain (domain)

Crypto ipsec transform-set vpn1 esp-aes 256 esp-aes-hmac

interface tunnel 100
ip address (a private business address)
tunnel source gi0/0
tunnel destination (whatever IP that Router 2 receives from its ISP modem, which is a public IP address)
no shut
Any assistance would be greatly appreciated. Thank you and have a great night.
