Alright, understandable.. Thanks for the information Currently I can't really test that DHCP issue since I replaced all devices recently that have a static DHCP address. But in case I have the time...

@Clive_A As we wrote here I have a question to the ER7412-M2 about the firmware updates.. just don't wanna full fill now the other ones inbox.....

Since many providers are slowly going to turn iPv4 off it may be a good idea to already start with testing/ adding functionalities like NAT64 and DNS64 to make it possible to use on the users end...

@Clive_A The ER7412-M2 has the same issue I can only change "fixed" DHCP addresses effectively after rebooting

Also ich habe es so gemacht zum Router hin sind alle VLANs getagged und zum Access Point alle bis aufs Verwaltungsnetzwerk

@Philipp_R Gerne, ich kann ja mal schauen vielleicht fällt mir noch mehr ein falls es nicht geht
