Given Tunnel Interface IP is wrong but still tunnel is up

L3 Networker

I am seeing the Ip address give to the tunnel interface is wrong ( for the tunnel with AWS) , but tunnel came up and working without any issue.

Can anybody suggest on this. Would the IP address which we will give to the tunnel interface would not matters.

Hi @Sujanya ,

 

The IP address on an IPsec tunnel is optional.  A standard site-to-site VPN does not require a tunnel IP address.  https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-admin/vpns/set-up-site-to-site-vpn/set-up-an-ip...  (Step 3)

 

Since the tunnel is point-to-point, all the NGFW has to do is route traffic down the tunnel and it will be received on the other side.  No routing to IP addresses is needed.

 

Thanks,

 

Tom
