Re: 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.

Anyone know if Verizon static IP's over LTE have same issue where they
bounce the traffic around before it gets back to the NY metro area?

All,

Thanks for all of the feedback. I was on site today and noticed two
things.
1) As someone mentioned it could be for static IP's they have the traffic
going to a specific location. The POP is in NJ there was a min. latency of
120ms which prob had to do with this.
2) I was watching the ping times and it looked something like this:
400ms
360ms
330ms
300ms
260ms
210ms
170ms
140ms
120ms
400ms
375ms

It seems to have been coming in "waves". I assume this has to do with
"how cellular work" and the signal. I tried moving it around by putting it
down low on the floor, moving it locations etc. and saw the same thing
every time. I am going to try Verizon next and see how it goes.

When SSH'ing in remotely the connection seems rather slow.

Perhaps using MOSH can help make the interactive CLI session less
annoying.

Verizon they charge $500.00 just to get a public IP and I want to avoid
that if possible.

You might look into have it call out / maintain a connection back to
your infrastructure.
