I'm not connected to 44net anymore, when I ping, to me at least, my
outgoing packets look correct, but I get no response ever.
I'm trying to put together as much as I can. My gateway ips 44.4.28.50
at 50.79.209.150, I have a static IP.
I'm current on the portal, far as I can tell with no error messages.
ping 44.0.0.1
PING 44.0.0.1 (44.0.0.1) 56(84) bytes of data.
*no response ever
I see the outgoing, but never the ping back.

I occasionally see one of these, which hints to me that ipip is making
it to my gateway.

I don't think it's a firewall issue, I've turned off firewall and it
doesn't fix anything.
My route table looks healthy, so I think ampr-ripd is worrking correctly?
Tried to include as much information as I can, thanks for any help!
