[44net] Anyone running an open AMPR VPN willing to share?

Hello Everyone, I'm helping out a local HAM getting an IPIP AMPR setup working but his current AT&T Uverse / Pace s 5862ac unit doesn't seem to be playing nicely. Yeah.. I know.. Shocking! Anyway, touter/NAT mode seems to *only* want to forward TCP/UDP protocols (typical) and it's DMZPlus feature mode seems to be breaking his Wifi network. As we maybe hack with the DMZplus feature tomorrow, I was curious if there is anyone willing to offer up a VPN connection to his Raspberry Pi as a Plab-B: Looking through the archives, there was http://wiki.ampr.org/index.php/AMPRNet_VPN but that link is 404. I know there is also the http://wiki.ampr.org/wiki/AMPRNet_VPN link but I know other HAMs are/were offering less complicated setups. I can help him setup any offering be it IPSEC, SSL-VPN, etc. He's not looking for any sort of performance.. just general IPIP access to play around, etc. at the moment. If already hosting or you're willing to host a solution, let me know. Thanks! --David KI6ZHD
