routed network, Crossroads running 3.9 or 3.10 for clients, 10.x.x.x for my AP subnets and 192.168.88.x for my client’s side, NAT masquerading on the client side, works fine.
For my customers with routers, I use pseudobridge, and I have about a 50% drop in speed. I’ve played with the MTU on the customer’s router, seems a little better, but “ping -f -l 1472” pings through without problem in the first place.
I’m tempted to disable DHCP in their routers and use it as a four port dumb wireless switch and have all the clients the same, but I’d rather they have access to their own router than have my Crossroads handle it.
