A sunny good morning everybody!
I just got my hands on Swisscom "Mobile Internet" using Sierra Wireless Compass 855.
With the "normal" "private" mode they put you in some 10/8 network and do NAT.
Just as a normal 08/15 I experienced that booking a ticket on sbb.ch can be almost impossible, as sbb.ch either has a session handling problem or swisscom has a nat handling problem (maybe a bit of both). Interestingly, I also often experience the "your session is invalid/timed out" message from sbb, when just accessing the timetable function.
Other than that I see that my (idle) ssh connections get cut (600 seconds works < cut < 1000 seconds idle does not work).
As far as I can remember, Orange always provides you with a non-rfc1918 ipn.
Can somebody confirm that behaviour and/or report what happens with the other providers?
I am now testing their "Corporate Application Access", which simply means "got a real username, got a real password and a different apn" which results in a (fixed?) non-natted ipn.
Sincerly,
Nico
