mtu with vlan enabled

after enabling vlan on station I can’t access it via web (or ssh) v1.2.3.
Would it be possible to increase mtu by 4 bytes automatically when you enable vlans?

Also, I’ve set 1550 mtu on v1.0.3, did a soft upgrade to 1.1.7 and to 1.2.3, seems like the settings are not saved.

There probably is no way now to change the station mtu remotely, right?
