MikroTik

My friend use MikroTik to share his ADSL internet connection, he use hotspot server on wireless. So, usually user need PC and then open a browser to login (get internet access).
But i want to share the internet connection with my RB433UAH (already support WLAN) to my laptop and 2 PCs, i want my friend set an exception for my mikrotik (maybe using mikrotik mac address), so no need to do hotspot login on my computers, what i have to do just firewall-masquerade mikrotik wlan connection (srcnat) and set routing.

Please help me..
thanks!!

On the Hotspot server enter an IP binding for the MAC address and IP address of your 433 with type bypassed.

On your 433 set a static IP on the interface that connects to the Hotspot server, set a default route through the IP address on the Hotspot server interface, and enter a masquerade action rule in the srcnat chain with an out-interface set to the interface on the 433 that connects to the Hotspot server.
