Is there any device can use any of 2 difference ip address to joint to a lan port.
Example my NAS only have one lan port Ip
I add a device so it became two lan port IP another IP from two difference network..
So I can access to by using  IP or IP

Note: I not allow to installed a router in the network.

You can just pick up a little 5 port switch.  Those are pretty cheap

You could use 2 routers for this setup (which by itself seems quite weird).
Router1, LAN address (assuming this is a free address), WAN address, set DMZ rule to forward all to
Router2, LAN address (assuming this is a free address), WAN address, set DMZ rule to forward all to

Now a computer on the WAN side of Router1 (ex. PC with IP can access the NAS on and a computer on the WAN side of Router2 (ex. PC with IP can access the NAS on

This is all assuming the NAS really can't have another IP address.
Another way is to have the PC's have 2 IP addresses (From Windows xp upwards, if you fix the IP address), connected by normal switches.

go to LAN properties - TCP/IP V4- first configure the lan settings on the network any of one...

i.e with dns and gateway etc.

then go to advanced settings

add additional ip ...

see the attached image..  this way you can access 2 networks on single lan...

all the best...
