@Carsten-Aa1 in controller mode look under network security and firewall, you should also upgrade the firmware on your router

To downgrade to the previous version, you can use the roll-back function from the Router console, SSH into the router and run the roll-back.

@GRL It's SD-WAN that I've been looking forward to the most, so hopefully it will come to the other routers in beta soon. Too bad you had problems with your upgrade, hopefully a fix will come pretty...

@GRL Ok so you have an ER7206 too :-) have you tested SD-WAN, I only have the ER8411 which has SD-WAN support but need an update to the other routers to test

@GRL I tested L2TP here, everything works as it should, both ER8411 as L2TP client and Server, connected Windows 11 pc with L2TP to ER8411 Server. I can't test routing on LAN but I have some routing...

@GRL I did a test here when I saw you were having problems, I can confirm that it is not possible to downgrade, for me everything works as it should so I hope I don't have to downgrade. :-)
