Answer : Pix 501 Remote Access VPN Issue
ISAKMP: transform 1, ESP_AES
ISAKMP: attributes in transform:
ISAKMP: authenticator is HMAC-SHA
ISAKMP: key length is 256 <<<---
ISAKMP: encaps is 1
ISAKMP: SA life type in seconds
ISAKMP: SA life duration (VPI) of 0x0 0x20 0xc4 0x9b
ISAKMP (0): atts are acceptable.
ISAKMP (0): bad SPI size of 2 octets!
ISAKMP : Checking IPSec proposal 3
ISAKMP: transform 1, ESP_AES
ISAKMP: attributes in transform:
ISAKMP: authenticator is HMAC-MD5
ISAKMP: key length is 128 <<<---
ISAKMP: encaps is 1
ISAKMP: SA life type in seconds
ISAKMP: SA life duration (VPI) of 0x0 0x20 0xc4 0x9b IPSEC(validate_proposal): transform proposal (prot 3, trans 12, hmac_alg 1) not supported
It looks like the client does not support AES-256
suggest changing your transform-set to 128 bit default aes
crypto ipsec transform-set ESP-AES-256-SHA esp-aes-256 esp-sha-hmac
crypto dynamic-map outside_dyn_map 20 set transform-set ESP-AES-256-SHA
TO:
crypto ipsec transform-set ESP-AES-SHA esp-aes esp-sha-hmac
crypto dynamic-map outside_dyn_map 20 set transform-set ESP-AES-SHA
