several IKE Crypto Profiles on the same interface for SITE-to-SITE VPN

L1 Bithead

Hello dear colleagues,

 

according to the documentation, there is a limitation for IKE gateways:

All IKE gateways configured on the same interface or local IP address must use the same crypto
profile. (c) 

The same restriction is mentioned in the PANOS v8.1 course.

 

First of all, it seems strange that we cannot use different IKE options for different peers. Second, I use different IKE Crypto Profiles for different IKE gateways on the same public interface without any problem. I can see that they do use different algorithms for encrypting, hashing, DH group, etc. So it works.

 

  Is it some obsolete information they just forgot to remove? 

 

Regards,

Vladimir Stepanov

Can you point out where it is in documentation?

You can definitely use diferent crypto profiles on same interface in diferent IKE gateways.

@vladimir.stepanov,

As @Raido mentioned this is either poorly worded or simply not correct. You can only assign one profile per IKE gateway (obviously), but as long as you use a different IKE gateway you can have multiple profiles assigned regardless of them sharing the same physical interface. 

At first I have seen it in the paloalto online course for Pan-OS 8.1, module about Site-to-Site VPN, IKE Gateway configuration. After I started to search and found the same in the PAN-OS Admin Guide 8.0 - Page 691

???

 

I have never seen or heard of this note and since 5.0 I use different profiles for the ike gateways ... also with 8.0

Definitelly a mistake. This would make firewall practically useless for VPNs.

Ok, thanks everybody, I am going to report them about this mistake. Just strange that this is mentioned in several sources.

Also on 9.1. Admin Guide site 907.

 

After Upgrading from working 9.0.8 with multiple IKE crypto profiles on same Interface / IP I got an auto commit error.status auto commit job public.JPG

Are your peers configured with dynamic IPs?
