IPSec tunnel between PA-220 and VM300 in Azure

[anthony.goethals]

Trying to build a IPSec tunnel between a lab PA220 and a VM300 we have in operation in an Azure environment.  I think I've got all the necessary ingredients covered, and I've checked all the "How To" docs I can find, but still no luck.

Are there any gotchas related to this kind of setup that I should know about as I proceed?  Any advice would be helpful.

Hello,

What are you seeing in the logs, traffic and system? The system logs show the VPN connections. Also not sure about Azure, but Google and AWS have load balancers in front of the hosted VM's, may want to double check and see if those ACL's are open?

If no interesting traffic then tunnel is down.

You can initiate tunnel on one side with command:

> test vpn ipsec-sa tunnel <tunnel-name>

And check logs at other side.

Whats the stae of your phase 1 ?

Is the issue with phase 2?

One recommendation is to use proxy ids with Azure, I know proxy ids ar eonly for cisco devices but this is one exception to the rule. 

I wish I could help more but having more details would come in handy.

From the PA220 I can test the vpn and I see it initiate but I can't find anything in the VM300 logs indicating failed connection attempts.  We might not have a policy setup yet to show the connection attempts.  Our Azure fabric is in production and used for a great many other things at this time --- not just for the Palo.

I did make sure in the Azure fabric to allow ipsec connectiivty through the public facing interface with a inbound port rule, but not sure if I did enough to allow connectivity.  I've approached this mostly as a Palo-to-Palo tunnel peer connection setup, so not sure if I've done my homework on the Azure side.
