Phase 2 fails [NO_PROP_CHOSEN]

Lybra1983
Level 1
Level 1

Hello,

I was testing a particular configuration with dynamic maps for soho routers and it worked well... see this post for the conf: https://supportforums.cisco.com/message/3265755

Since a few days I'm trying to port this configuration on a productive appliance (ASA5510 - v8.22) and it's not working.

The only difference is that the ASA5510 is already configured to allow access to users with vpn client.

The Zyxel router is telling this: (read it from bottom to up)

Send<:[HASH][DEL]>
Recv<:[HASH][NOTFY:NO_PROP_CHOSEN]>
Send<:[HASH][SA][NONCE][ID][ID]>
Start Phase 2: Quick Mode
Phase 1 IKE SA process done

The show isa sa on the ASA it telling this:


IKE Peer: ***.***.***.***
Type    : L2L             Role    : responder
Rekey   : no              State   : AM_WAIT_MSG3

And this is a piece of the conf:

crypto ipsec transform-set trmset1 esp-aes-256 esp-sha-hmac

crypto ipsec transform-set dynset esp-3des esp-md5-hmac

crypto ipsec security-association lifetime seconds 28800
crypto ipsec security-association lifetime kilobytes 4608000

crypto dynamic-map map2 10 set transform-set trmset1
crypto dynamic-map map2 10 set security-association lifetime seconds 28800
crypto dynamic-map map2 10 set security-association lifetime kilobytes 4608000

crypto dynamic-map DN3710 2 match address ST_3710
crypto dynamic-map DN3710 2 set transform-set dynset

crypto map yyymap 10 ipsec-isakmp dynamic map2
crypto map yyymap 11 ipsec-isakmp dynamic DN3710

crypto map yyymap interface outside

crypto isakmp enable outside
crypto isakmp policy 1
authentication pre-share
encryption 3des
hash md5
group 1
lifetime 86400

crypto isakmp policy 2
authentication pre-share
encryption 3des
hash md5
group 2
lifetime 86400

crypto isakmp policy 10
authentication pre-share
encryption aes-256
hash sha
group 2
lifetime 86400

crypto isakmp policy 65535
authentication pre-share
encryption 3des
hash sha
group 2
lifetime 86400

I can't figure out where the problem is. Any idea will be appreciated!!!

Thanks in advance for a help.

Regards,

Luca

The Zyxel only accept a simple AES, not 192 and not 256, anyway I changed the transform set from 3DES/MD5 to AES/SHA and put an appropriate policy, but the error messages are always the same.

You can post your current config of both sides with the errors on both sides as well.

Hi Federico,

I should read posts better    you were right indeed it is not a phase 1 problem
