Just a quick question. I've been considering a move to AX series, or going with my own SBC router I build from scratch. The difference in question is simple: I can go pure layer 3 isolation across devices or I can go with layer 2 (vlan) network isolation.

AX series (as with most recent Asus routers) do not have a working robocfg as I understand, which means no realistic vlan tagging at ports.

I took a look at the ip(6)tables and ebtables isolation model in a default "multiple guest network" setup and frankly it's ok, but somewhat trivial (i.e. weak, but kinda works). It will need a lot of custom upgrades for what I'm doing.

So - the question is this: has everyone but me already acquiesced to layer 3 isolation? If so, it's not a problem, I definitely prefer to buy another Asus (AX) router and keep asusert-merlin software, but hope to understand others' experience with rather extensive layer 3 isolation customization (I'll need a lot).

Thoughts?
