It appears traffic shaping only works if a complete address with mask is configured in the traffic shaper section. How would one set up persistent IPv6 shaping when dealing with dynamic prefixes?
Guessing there is currently no way but to update the IPv6 traffic shaping rules manually?
In the advanced section of the rules, you can select traffic based on direction, so that way you don't have to deal with addresses.
Cannot believe I missed that! The option was conveniently hidden under the advanced toggle, but it works perfectly as one would expect. Thanks for your reply!
