Guest_turris exceeding character length (11) of LuCI Firewall zone name

It appears that the LuCI firewall zone name is limited to 11 characters. Exceeding it renders the name box with a red border and also the typed in name. Trying to save such zone (changes) pops up a java script window citing

Some fields are invalid, cannot save values!

The zone name guest_turris generated by TO as default for a guest network comprises of 12 characters however and thus is deemed invalid.

It begs the question whether that is only pertaining to LuCI or whether UCI cannot interpret zones exceeding 11 characters and thus rendering the entire firewall zone obsolote?

Hello,

We have looked at this issue. This seems related to LuCI, because we’re using firewall3 and it has the maximum length for firewall zone, which is 14 characters.

You can see it here.

// EDIT: I’m responding to your issue. I’ll reply to another topic, soon.

If you consider the aforementioned bug report by @Faexa than it would appear not just being a bug in LuCI
