IPsec VPN with AH generates core files

L1 Bithead

Hi team, 


I have two VM-50 v9.01, one in SiteA and another in SiteB. I set up an IPsec tunnel between them with: IKE-v1 : phase1 (aggressive mode)  and phase2 (quick mode) with ESP.  it works fine and I'am able to ping from a vlan in SiteA to another vlan in SiteB . 

I wanted to test AH instead of ESP. However everytime I want to send a ping from SiteA to SiteB, the firewall in SiteB craches and generates a core file. 

If I perform a "test vpn ike-sa gateway mygateway" and "test vpn ipsec-sa myipsec" it works fine and I can see the SA created in both firewall. However when I send a packet from SiteA to SiteB, I can see the packet leaving firewall in SiteA with the apropriate AH header inserted. But as soon as the packet arrives in the firewall in SiteB, it craches. 


I can provide pcaps and core files , or anything you may need to help me.

Does anybody try to do the same ? 

Any help would be appriciated 

Many thanks

It would be odd to have two PA devices utilize AH. I would open a ticket with support and see if they can duplicate the issue; it sounds like it may be a bug with 9.0

Hmmm as I said in my description I am in a lab environment and I wanted to test different configuration to make sure that I'm doing things right, I don't think that the support would accept my issue as a "ticket" ... It would be nice if anyone could try to setup AH between two Paloaltos and keep me in touch if it works for him. 

Many thanks,
