Hi! I will try to give a description of the problem here. First the setup:
I have a RUTX09 with a LTE sim card that has a IPsec tunnel to a firewall at work. The RUT connects with the IPSec just fine and everything looks solid. I can even remote log in to the RUT interface via the tunnel.
However when I put a computer on the lan port, I don't recieve any internet. I am not able to log into the RUT interface locally, unless I remove the SIM-card, then the local access works. As soon as I put the SIM-card in, It throws my computer out of the interface. While the SIM-card is in, I do get IP and gateway is correct, but I am not able to ping the RUT locally.
I have compared the device to another that has identical settings (except different IP subnet) and that one works great.
Cheers for any help
