Hello

we have some gateways that are often offline. Some days it works and some days are longer offline.  
On console we can see anything like:  
Last Seen 20 hours ago  
Last Seen 22 hours ago  
[…],  
sometimes it works a few days and on other days the devices are offline for more days.

We have as uplink a VPN on all devices and they have the same public IPv4 address (NAT) and a smaller MTU (most 1412bytes). I am not sure if it is because I suspect the error somewhere there.

As device we use Raspberry Pi with ic880a-spi, mikrotik and ttig, all devices have the same probleme

Here some Gateway IDs with the problem:  
eui-3135323562003c00  
eui-323433365d003500  
eui-58a0cbfffe8013f0  
eui-b827ebfffec3ceaa  
eui-b827ebfffefc7663

anyone any ideas what i can do? On the ttnmapper, the devices are often offline too.

On a self hostet chirpstack, the gateways works fine (i use ipv6 here).

I hope someone has an idea here.

Christian

Are the gateways forwarding data even if listed offline? If that is the case you might want to take the second message at [the status page](https://status.thethings.network/) into account…

No i get no data from nodes if the gateway is offline
