Hello everyone, I hope you can help me. These are the first Sophos firewalls I'm configuring.
I have the following hardware constellation: The Draytek Vigor 165 is used as a pure VDSL modem in full bridged mode, connected to it is a XG 115 rev. 3 with the current SFOS 18.0.0 GA-Build379. The Sophos dials in via PPPoE to the internet provider, which works, at least for a not clearly defined time. Then the connection is terminated and the Sophos redials. The whole thing happens at very different times.
It worked last weekend, but as soon as you start working on the network again, the connection is lost again. There may be up to 10 or more new dialins per day. This behavior occurs at all three locations with two different ISPs.
I have adjusted the MTU value to 1492 according to the provider. The following is an excerpt from the networkd.log
ip_choose_hook is NULL
Plugin /lib/rp-pppoe.so loaded.

pppd 2.4.7 started by root, uid 0
Interface Port2 has MTU of 1492 -- should be at least 1500.
This may cause serious connection problems.

I would be very grateful for help or tips. If you need more logs I can provide them.
