Look at your MT log. Most likely a NAT issue through the Onstar crap.
You'll probably see key exchange timeout or something like that. I
forget what exactly since the last time I debugged it. L2TP/IPSec won't
work through my Canopy SM NAT or R200 either, I haven't bothered to
figure out which it is yet.

I can�t be the only one that has tried to do this on the list. My
newest Chevy truck came with onstar wifi free for three months. On a
daily basis I tether up to my Verizon phone and VPN into our microtik
routers with my laptop. However when I connect up to the onstar and
try to VPN I get the attached screen cap. Pretty much error code 800
VPN tunnel failed. I have played around with the encryption types and
so on our of desperation I have talked to two different �techs� at
onstar and I feel I may have lost all hope in hunmanity at the very
least I lost an hour of my life. I did learn that Onstar wifi is
provided by ATT cellular. So I am reaching out to the list to see if
there is something strange / blocked on ATT that wont allow VPN into
the microtik? According to onstar �they don�t block anything�.
Anyone have any thoughts? It would be nice to be able to make this
work so I can buy some data to use when outside of Verizon coverage
but still covered by ATT / Onstar.
