IKE gateway is not allowed

Hi all, 
I've just installed a PA 3220 and there're dynamics VPNs tunnel. IKEs are up. However,  phase 2 (tunnel) aren't coming up. 

 

Looking at the logs I see the following logs for all VPNs .
"initiate negotiation to dynamic peer from IKE gateway is not allowed"

 

 My outside interface is allowing IKE and IPSec, I don't see packets being dropped.

That's what I can see on the logs

Re: IKE gateway is not allowed

Whatever firewall is the dynamic peer needs to be the initiator of the VPN tunnel and not the responder. Ensure that you don't have the "Enable Passive Mode" option checked.

Re: IKE gateway is not allowed

The Enable Passive Mode option should be checked on the non-dynamic addressed firewall and not on the dynamic remote firewalls?

"With this option enabled, the firewall responds to incoming connection negotiations as it would normally do, but it will no longer initiate outgoing negotiations. "

@jeremy.larsen,

Correct. On the non-dynamic firewall you want passive-mode enabled, and on the dynamic firewall you want to ensure that passive mode is not enabled. That will ensure that only the dynamic firewall is attempting to establish communication with the non-dynamic firewall, which works perfectly fine.
