Supply the following if possible:

  • Device problem occurs on: This is a x86_64 VM running under KVM
  • Software versions of OpenWrt/LEDE release, packages, etc.: Default packages that come with the 21.02 qcow2 image
  • Steps to reproduce...

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 it seems it wouldn't work even if you enabled it as the port is 33434:33689 rather than 33434-33689
is this reported anyplace... could I report it, and where would I?
Lantizia: is the place for reporting issues
we'd appreciate the report :) Thank you for finding and mentioning!

Not sure if it's just LuCI that doesn't like the ':' character or if it's also an impossible firewall rule without LuCI also. But certainly with LuCI you can't edit and save this default rule without also fixing that character as the field box comes up red as though the contents are not valid.

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