PA to Cisco 5505 VPN tunnel

[infotech]

When trying to configure a site to site VPN tunnel from a PA 3020 to a Cisco 5505 firewal I am getting th following messages on the Cisco firewall

received encrypted packet with no matching sa dropping

all ipsec proposals found unacceptable

[HULK]

Hello Infotech,

Could you please clear the IKE and IPSec security association (SA) on both firewalls and then initiate the tunnel once again.

For example, in PAN FW:

clear vpn ike-sa gateway XXXXX

Delete IKEv1 IKE SA: Total 1 gateways found.

> clear vpn ipsec-sa tunnel XXXXXX

Delete IKEv1 IPSec SA: Total 1 tunnels found.

> test vpn ike-sa gateway XXXXXX

Initiate IKE SA: Total 1 gateways found. 1 ike sa found.

> test vpn ipsec-sa tunnel XXXXXX

Initiate IPSec SA: Total 1 tunnels found. 1 ipsec sa found.

Also, verify if there are any IKE session in discard state between the gateways.

Thanks

[infotech]

I cleared on the PA side but have to lookup how to do it on the Cisco side

This is what I got when I did the test vpn ipsec-sa tunnel

Initiate IPSec SA: Total 12 tunnels found. 12 ipsec sa found.

Looks like you might have mismatch between the proposals configured between the two devices . Make sure the proposals chosen on both sides are matching ( Encryption, Authentication, DH Group , life time and life size)

[infotech]

That was my first thought and I could be missing something but they look the same as far as I can tell. It looks like to me it is failing on phase 2 any suggestion on where else to look on the PA or the Cisco I would appreciate

Have you reviewed the IKE log on the 3020

from the CLI

less mp-log ikemgr.log

What do you have set for your proxy-ids on your 3020?

[infotech]

Here is the result of running less mp-log ikemge.log

Phase 2 Mismatch

notification message 14:NO-PROPOSAL-CHOSEN

What is the transform set on the ASA for this network?

What is your corresponding IPSEC policy on the 3020?

Sample IPSec Tunnel Configuration - Palo Alto Networks Firewall to Cisco ASA

[infotech]

What is the transform set on the ASA for this network? ESP-AES-256-SHA (IKEv1) PFS-group1 (looking in the crypto maps)

What is your corresponding IPSEC policy on the 3020? ESP-AES-Sha1 (ipsec crypto)

[jcostello]

IPSEC Crypto Profile on PA defaults to group-2 (group 1, group-2, group-5 and group-14 are available)

The ASA is indicating group 1

[infotech]

I have the ipsec crypto set to group 1

[jcostello]

From the 3020 CLI - please provide the output for your profile configured for IPSEC

set cli config-output-format set

configure

show network ike crypto-profiles ipsec-crypto-profiles

from the ASA

gather the line that starts with crypto ipsec transform-set that is configured for the crypto map

Thanks

[infotech]

Here is from the PA

Cisco - I am not 100% sure what you are asking me to do here so I just look in the ASDM under site to site vpn\configuration cryptop maps

transform set ikev1 ESP-AES-256-SHA

[jcostello]

On the ASA CLI or the configuration output I was looking for the assigned transform set

Which of the crypto profiles on the 3020 is assigned to the VPN that is having issues

[infotech]

right now its this one

set network ike crypto-profiles ipsec-crypto-profiles Herget_Standard_IPSec_Crypto lifetime hours 1

But I also tried this one too

set network ike crypto-profiles ipsec-crypto-profiles Herget_Standard_IPSec_Crypto-1 dh-group group1
