I do wish they made it a bit more "carrier" in that regard. I use PPPoE because I can control everything that way, but it sure would be nice to use something to control all of that business, then let their device manage IPs... just like cable.

There could be one NAT, at the access point. My taste, which to be sure I haven't tested at scale in a wireless network (but plan to), is to follow what is becoming standard wireline practice and do switching, not bridging, at "layer 2". Routing would then be lumped into one place, making it easier to manage. The problem with small Linux-based systems (this includes both UBNT and MT) is that they don't tend to have switching documented or set up in the UI, even if it's possible. Bridging is bad -- it was designed for orange hose Ethernet, and it passes broadcast traffic to everyone. We invented this at DEC in the 1980s and discovered how it doesn't scale too well -- we had a couple of thousand DECnet and IP nodes on a bridged LAN, and the background broadcast traffic level was 400 kbps. This was a lot for systems to handle in 1991. I was testing ISDN bridges and "discovered" how you can't just bridge that type of network across a 56k connection. (I discovered the traffic when I first turned up the bridge. I ended up isolating it behind a router, built from an old VAX. At DEC, we built everything ouf of VAXen.) Switching, though, is what Frame Relay and ATM do, and now Carrier Ethernet is the big thing for fiber. It uses the VLAN tag to identify the virtual circuit; the MAC addresses are just passed along. Since it's connection-oriented (via the tag), it can have QoS assigned. I think it's theoretically possible to tag user ports, route on tags and set QoS on RouterOS, but it's not obvious how to do it all. Switching doesn't pass broadcast traffic; it provides more isolation and privacy than plain routing. Mesh routing then works at that layer, transparent to IP. It'll be "interesting" to set up.

Same benefits others mentioned for routing, just one fewer NAT. Never have a problem with it this way and can't see any good reason to NAT there.

He have heard other wisp are using the Ubiquiti radio as a router. Would like feed back why one would do this when it appears customers would be double natted when they hook up their routers? Or does it not matter from the customer experience? Thanks -- Arthur Stephens Senior Sales Technician Ptera Wireless Inc.
