VPN ASA with Fortgate

[marcio.tormente]

Hello Folks!

I always have problem with VPN...LOL

I create a new VPN site-to-site between ASA 5510 (IOS 8.42) and Fortgate, but something is very strange, the VPN don´t come UP and I see in the debug crypto ikev1 10 the folow log:

 [IKEv1]Phase 1 failure: Mismatched attribute types for class Gr oup Description: Rcv'd: Group 1 Cfg'd: Group 2

But if I ask the other peer to change to group 2, the msg in the ASA is: 

 [IKEv1]Phase 1 failure: Mismatched attribute types for class Gr oup Description: Rcv'd: Group 2 Cfg'd: Group 1

Fortgate is possible to enable both to specific VPN group 1 and 2, and I ask to the other peer to left this way and the ASA show:

 [IKEv1]Phase 1 failure: Mismatched attribute types for class Gr oup Description: Rcv'd: Group 2 Cfg'd: Group 1
 [IKEv1]Phase 1 failure: Mismatched attribute types for class Gr oup Description: Rcv'd: Group 1 Cfg'd: Group 2

The show isakmp sa:

9 IKE Peer: 179.124.32.181
Type : user Role : responder
Rekey : no State : MM_WAIT_MSG3

I delete and creat the VPN 3x and the same error occur.

Anyone saw this kind of problem?

Perhaps you could post your crypto config?

Hello Richard!

Thanks for your support

Follow the config:

crypto map outside1_map 1 match address outside1_cryptomap
crypto map outside1_map 1 set pfs
crypto map outside1_map 1 set peer 179.124.32.181

Phase 2 is group 2 as well.

[Aditya Ganjoo]

Hi Marcio,

Please configure similar policies for group 1 in phase 1 as well.

crypto ikev1 policy 7
authentication pre-share
encryption aes
hash sha
group 2------create similar policy like this but change the group to 1 
lifetime 28800

Let me know if it works.

Regards,

Aditya

Is this using Fortigate version 5 by any chance?

I have seen VPN issues with Cisco ASA's on numerous occasions with this Fortigate code, though mainly this has been a Phase 2 issue and setting the KB lifetime to maximum on the ASA side has resolved it...however this seems not to be your issue here.

First thing from your config though, I see you have PFS enabled - have you ensured this is set on the Fortinet side, or tried turning it off on the Cisco side to see if that comes up?

Being stuck at MM_WAIT_MSG3 means that you have sent back your policies but then you have not recieved the third packet in the ISAKMP exchange so either the Fortigate is unhappy about something or there is a routing issue (though, unlikely since you have already had communication)

Try on the ASA side:

debug crypto isakmp 7

Also can you confrm that your outside interface is 'outside1'? You can see this from 'show ip'

Hello David!

Thanks for your support

I saw some people on the internet with lifetime issue and I change this on ASA, but the result stil the same.

PFS is enable because the other side asked me to enable, I have 18 VPN in this ASA and only this new was asked to enable PFS.

I told the other side about the MM_WAIT_MSG3 and he told that in his side is everything okay, we compare all the settings and seems is the same.

Follow the result of degubug isakmp 7

Yes, the interface is outside1, I have the outside as well, but everything that is in the outside interface, I hhave to migrate to outside1 (New Link).

David,

Was routing problem, but in the Fortigate side.

thanks

[Richard Burts]

Thanks for posting back to the forum and letting us know that you have solved the issue and that the problem was a routing issue on the Fortigate side.
