Hello everybody,

I just can not get on with one thing ...

I've set up an L2TP connection following this guide because the USG is behind a router:

It worked well and I can now connect to the network with my mobile phone or laptop. The problem is, however, that the connected devices in the network have since no Internet. But if I set the DNS server to in Interface for LAN1 instead of "Zywall" and deactivate the SSL inspection, it works. Before that, the DNS server was set to "Zywall" and the SSL Inspection enabled and everything worked great. In addition, I noticed that the USG itself seems to have no Internet. Maybe I'm just too stupid and overlook something here. Thanks very much for an answer!

Kind Regards,
