IR-809G / LTE Connections work but no Incoming pakets

Hello,

we installed a IR-809G-LTE router.

We get an IP on interface celle0 and we also have a default route to celle0.

The problem is if we try to ping outside we see that paket counters are rising for outgoing pakets but we dont see anything for incoming pakets.

So the connection to internet does not work.

 

The strange is that we have a similiar router with nearly identical config and here we see incoming and outgoing counter rising and therefore a working internet connection.

 

We replaced the affected one but this does not succeed.

 

So what for possibilities have we to check the router? Is this a problem with a config or a provider issue? How can we prove it if this is a provider issue?

Are there debug commands?

 

Working scenario:

sh int cell 0
Cellular0 is up, line protocol is up
  Hardware is 4G WWAN Modem - Global (Europe & Australia) Multimode LTE/DC-HSPA+/HSPA+/HSPA/U
  Internet address is x.x.x.x/32

  Encapsulation SLIP, loopback not set
  Keepalive not supported
  Time to interface disconnect:  idle 00:01:59
  Last input 00:00:00, output never, output hang never
  Last clearing of "show interface" counters never
