!--- PHASE 2 CONFIGURATION ---!
!--- The encryption types for Phase 2 are defined here.

!--- Define the transform set for Phase 2.

crypto ipsec ikev1 transform-set ESP-DES-SHA esp-des esp-sha-hmac 

!--- Define which traffic should be sent to the IPsec peer.

crypto map outside_map 1 match address inside_1_cryptomap

!--- Sets the IPsec peer

crypto map outside_map 1 set peer 1.1.1.1 

!--- Sets the IPsec transform set "ESP-AES-256-SHA"
!--- to be used with the crypto map entry "outside_map".

crypto map outside_map 1 set ikev1 transform-set ESP-DES-SHA

!--- Specifies the interface to be used with
