OpenWrt router acting as multiple devices?

[puydt]

Dear,

Would it be possible for an OpenWRT router to act as if it was multiple devices (multiple IP addresses). And forward the data to a different interface depending on what address was used?

For example I've got the router at address 192.168.0.1 as a DHCP server, with my devices on address 192.168.0.10 and further.
On a different interface there's a device on address 10.128.24.5.

Now what I'd like to do, is be able to access that device over the router by just addressing 192.168.0.5 from a local device.

Is this possible and how do I set this up?
Already tried static routes, but that doesn't allow for IP address conversions.

On the device it self give it the alias 192.168.0.5
