Hello, This is sort of a follow up to my last email, which I ended up figuring out. This link, http://he.fi/amprnet-vpn/amprnet-vpn-win.zip to download the amprnet crt file is invalid. Any idea where I would obtain that file from? Thanks! -Nate

Hi,
The download links for the VPN config files work again now. Sorry for the website outage; server migration taking a bit longer than expected due to Real Life Events (TM). :)
The included certificates are signed with weaker-than-desired hash algorithms, and modern TLS/VPN software are beginning to reject them. I suppose I'll have to make new ones soon and publish new config files along with them. The security issue is not that huge on AMPRnet use, but it'd be nice if it worked out of the box.

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!
