Has anyone been able to configure Unicast Reverse Path Forwarding in RouterOS?
I did some tests with on-demand Firewall Filtering rule activation (rules added on PPP Connection), but the implementation is tricky and can't cover all scenarios available in a PPP Authenticated Session environment (for example if a Framed-Route is dynamically assigned to a User via Radius and injected in the created PPP IF On-Demand).
The RPF feature is commonly used on Access Device Interfaces, basically to prevent Users IP Spoofing. For this reason I think it is in the Top5 entry of Network Administrator RouterOS WhishLists! :)
I see some related requests on some old post in this forum, but I can't find specific replies on this topic.
