port forwarding for a client behind hotspot

RouterOS General
1

Hello

this is my network scheme

ether1 : 192.168.10.10
GW : 192.168.10.100 (Internet)
ether2: 192.168.1.0/24 (HotSpot)

there is a server with ip 192.168.1.2

i want do port forwarding for server to be accessible via internet.
since the server is behind hotspot i have to add server’s ip to hotspot “make binding”. but i don’t wanna all of server’s traffic be bypassed.
how can i do it for specific port of server? 3389 RDP for example.

Thanks
