i do not. i manually manage these routes all by myself using systemd-networkd... these routes are respected but the via address is ignored nonetheless. to repeat myself, the via part of the route is not considered; i even double checked this by reading the code and furthermore did a PoC if it could be done. as soon as the route hits the interface the packets get routed according to the AllowedIPs setting regardless of any via address set on that route. If you are inclined enough to do so you can try it yourself. set it to a non existing address and you will see it will be routed regardless... or even set it to the address of an existing peer that has it set in its AllowedIPs setting and you will notice the peer that has the packets destination set as AllowedIPs setting will get the packets. which makes some sense as return traffic would only be allowed to come from that peer anyhow. i.e. for incoming packets the routing table is not even considered at all (analog to reverse path filtering).
