A bridge isn't required on MT at all. I usually assign separate IP space and adjust my firewall rules as necessary. The MT handles routing between the subnets.

If you want to be on the same IP space, just make sure you use a "reserved" part of the LAN subnet for PPTP and enable proxy-arp.

You don't need the bridge.  Create the VPN with an inside address in his

When you log in, you have a address in his range, so effectively you are 
"inside."

All subscribers have static nonroutable IPs.  All subscribers are limited to a 
contract speed.  Each subscriber's speed is limited in his own Mikrotik CPE.  
Since the host has no CPE, I limit his speed by a simple queue on the ethernet 
port.

The host's ethernet port is NATted to provide the host with a private address 
range for the devices inside his home, all the traffic from which shows up 
NATted to a particular subcriber-range nonroutable IP that identifies him.

All fine so far.

I need to set up a PPTP VPN so I can log into the router remotely for troubleshooting 
"as if I were" a device in the host's residence.  To do this, I put the 
ethernet port into a bridge (moving the address and the DHCP server target 
appropriately), then create a PPTP VPN that attaches to that bridge and shares the host's 
DHCP pool.

This all works, too, as far as function goes.

What doesn't work at this point is the simple queue.  If I leave the simple 
queue on the hardware interface, it limits the host's speed TO the network 
only.  If I change the simple queue to the bridge instead of the interface, it 
limits the host's speed FROM the network only.

If I create a simple queue on each, I can "make it work," but that "solution" 
strikes me as a kludge.  What am I doing wrong?
