I am not sure I understand IP Binding in the MT 3.1.1 router OS.

1) If I Put a HOTSPOT side IP address (eg: 10.40.50.200) into Hotspot/IP Bindings/ in the ADDRESS entry window, select SERVER=all and TYPE=BYPASSED, is this the setup to a) allow a device with address 10.40.50.200 to access through the hotspot without logging in or b) allow a device on the PUBLIC side of the router to freely access port 10.40.50.200 on the HOTSPOT side of the router or c) both of the above.

2) If the above is NOT the way for a PUBLIC side device to access a HOTSPOT side device on 10.40.50.200, then can someone shed some light on this problem?
Thanks!

The answer is a) allow a device with address 10.40.50.200 to access through the hotspot without logging in.

I think you meant to ask how can a PUBLIC side device access a device with ip address (not port) 10.40.50.200 on the private side of the router?
To achieve this, i think you will need to perform a destination nat, so that public side devices have their ip addresses translated to private addresses within the same subnet as 10.40.50.200

I believe you are right. I think I have to set up a destination-NAT. And maybe more than that. Can anyone either give me an example of the needed commands or point me to an example? I cannot seem to find an example of this construct in the MT manual.

Thanks.

Thanks.. That information was what I needed.
