I'm using RB850Gx2 (powerpc) with 6.34.2 installed. There is no any specific configuration, just DHCP, some NAT rules for port forwarding and some reserved IP addresses by MAC address.
What I want is allow use WAN IP addresses in LAN. For example - one NAS drive with IP address 10.0.0.39, I can connect to ftp by ftp://10.0.0.39:21 from LAN. I'm configured that IP address to port forwarding, so I can access ftp on that NAS from outside using ftp://some.ip.address:4040. But I want that I can access ftp from outside IP in LAN. How can I do that?
