Help with VPN between ASA and cisco 877

Hi, I am trying to move a Cisco 877 that is happily connected to a cisco concentrator over a DSL to our Cisco ASA.

I changed the 877's peer to the ASA and went through the ASA's VPN wizard in the ASDM and the tunnel didn't come up.

I take it the local network is my LAN IP range and the remote network is the LAN IP range of the 877?

The VPN info on the 877 is:

crypto isakmp policy 1

encr aes 256

authentication pre-share

group 5

crypto isakmp key abcdefg address



crypto ipsec transform-set CBSO_T_Set esp-aes 256 esp-sha-hmac


crypto map CBSO_Crypto_Map 10 ipsec-isakmp

set peer

set transform-set CBSO_T_Set

match address 101

The local IP range of the 877 is

My IP range on the inside of the ASA is

The peer IP of the 877 is

What should I add to the ASA is CLI or ASDM based on the above?

Make sure that the security and other configuration parameters such as the lifetime matches on both the sides. Also ensure that interesting traffic is allowed properly using access list on both the sides.
