Javier, There's really no good way to handle this without routing or tunneling that I've been able to find in a very long time. (SD-WAN can help, but it's just a fancy way to tunnel in this regard.) It's pretty amazing that this is such an issue, but it remains so. I have tried to work around this using BSoD ( https://specification-search.cablelabs.com/business-services-over-docsis-layer-2-virtual-private-networks ) but we eventually abandoned the effort because it rapidly became to expensive to scale to solve a niche problem.
