19.7 Legacy Series / Re: OpnSense to OpnSense VPN
« on: October 24, 2019, 05:44:42 pm »
I had basically this same issue doing a lab with Opnsense to Opnsense (both VM's within Azure). I could ping both sides of the tunnel interfaces from within each Opnsense VM, but nothing else. My issue was having not enabled 'IP Forwarding' on the NIC's of each VM within the Azure portal. Once that was completed, everything was accessible on both sides.
"Any network interface attached to a virtual machine that forwards network traffic to an address other than its own must have the Azure Enable IP forwarding option enabled for it. "

Hopefully this helps someone else.
