So I'd also add the overall limit of 2^16-1 there as upper limit in the schema and also assert <= $bridge_mtu on CT-start/veth-hotplug and possibly also on config change (to early catch it for stopped CTs already, as IMO its better to push the user towards setting the bridge MTU earlier than the ones of its connected ports. work flow nit: why bother adding this to the non advanced section only to move it immediately? I'd directly add it to advancedColumn1, if you want to move out rate limit field before or after is Am 17/10/2022 um 15:56 schrieb Daniel Tschlatscher:> The option to set the mtu parameter for lxc containers already exists > in the backend.

And while yes, one may use something different than IP for sending ethernet link stuff it seems rather unlikely in practice, so maybe go for 576 as min, if someone complains we can still lower that and then have an actual known use case. The backend can stay at 64 for now, as there we would need to wait for the next major release with a check for < 576 added to the pve7to8 upgrade helper script, as long as the frontend is restrictive from the beginning I think there won't be many cases that run into this check though.
