Nope, that's my firewall dropping that. I don't allow ICMP to hit the
96.86.86.53 address.
My tests included both PING and HTTPS. HTTPS is allowed through. The
bigger point I'm making here is that I ran TCPDUMP at the OS level which
would show the packets before the firewall rules are applied.
As a test, you can go to : https://96.86.86.53 This is my VPN appliance
and you will get a login page there. At least...you should.
Thanks

I've got the tunnel defined on my router.
When I run a TCPDUMP on the

obviously, am I seeing any traffic on my tunnel interface.
How do I troubleshoot this?
Thanks

Your cable modem/router is rejecting incoming packets from 169.228.66.251:

However, pseudo-RIP and IPIP are being sent to you, so once you fix the
problem with your modem/router you should be on your way.
