What do your logs say? Have you run a debug on the ike yet? If you are trying the connection take a look at the mp-log ikemgr.log and look at the messages. Watching that will give you a good indication where the issue might be.

Are you able to ping the public IP peer on the remote side? I would also go over your ike/ipsec settings from the vendor and make sure you are matched up.

look at the system logs and filter with (subtype eq vpn) .If you seel messages saying failing due to negotiation timeout then take a packet capture on palo alto and checkpoint to check if you are sending/receiving isakmp packets

Run a test vpn ike-sa gateway <gateway> and have a look at mp-log ikemgr.log for more info

Amaresh:

If you are using the Azure VPN gateway, try this KB article:

Unfortunately, the article doesn’t offer any help on how to configure the Azure side, it only suggests to read a Microsoft article that is very generic.

Please, give us a howto document with examples for both sides; otherwise, it is worthless.

In our reference architecture and companion deployment guide, we do not typically recommend terminating the VPNs on the Virtual Appliance running in Azure. This is b/c you will need to use SNAT to enforce return path routing through the proper firewall to prevent asymmetric routing as we cannot extend BGP from the firewalls to the Azure Route Table. Instead, you may consider terminating the VPN on the Azure VPN Gateway and use our backhaul routing design to force all traffic to and from the Gateway subnet through the firewall utilizing UDRs and the Load Balancer.

HI,

We are currently working design to use Azure as DR site. We stuck at the connectivity from our remote sites to Azure as all our remote sites are having ADSL connections with dynamic Public IP address which is not supported by Azure VPN Gateway.

We through for using Palo Alto firewall at Azure for on-premise connectivity but after looking at this discussion we have to rethink for that.

Can someone advise the best way to go? Alternate option is we can migrate our ADSL connections to Managed ADSL connection on which we will get single static public IP address, however additional operational cost involve in this option we are keeping this as a last option.

Thank you.
