Cellular backup connections

All,

I finally got around to putting in a Verizon LTE connection and the ping
times are pretty good. There is the occasional issue however for the most
part ping times are < 50 ms. I have another strange issue though. When I
try to ssh or connect via the endpoints web interface it fails. If I first
connect via PPTP or SSL VPN then it works. I ruled out it being my IP since
if I connect direct from the PPTP or SSL VPN box then it fails as well. It
seems the tunnel does something (perhaps lowering the MTU or fragmenting
packets) that allows it to work. Any thoughts?

TIA.
