As mentioned on IRC/OFTC...

hmm there is a broken default 'Traffic' Rule' of 'Support-UDP-Traceroute' on 21.02
which is disabled by default... but wouldn't work even if you enabled it as the port is 33434:33689 rather than 33434-33689
is this reported anyplace? I could report it... but where would I?
Lantizia: is the place for reporting issues
we'd appreciate the report :) Thank you for finding and mentioning!

This new default firewall rule (although disabled by default) seems to have been introduced with commit de8b88c.

I'm not sure if the colon (rather than a hyphen) affects the possibility of this rule working if it is activated without using LuCI.

But certainly from within LuCI... if try to edit this rule and re-save it (without changing anything) then it'll flag the field as having invalid contents and refuse to save.

If colons are valid in this context then I'll re-file this bug to the LuCI bug tracker instead.
