one-ne-one NAT ?

On a community WAN that is in 192.168.3.x/24 range I have 4 Clients (Senao bridges), say 192.168.3.11-14 and a Company 192.168.3.10 (Mikrotik) with internal LAN address of 10.0.0.240/24

Now they want to use the 192. machines as if they were connected straight to the 10.0.0.x LAN with own IP address. So i want to set up one-on-one NAT where if they from LAN ping 10.0.0.241<-> 192.168.3.11, 10.0.0.242<->192.168.3.12 responds etc.

I read the manuals on src / dst nat and tried a few things, but could not get it to work…

How can I do this in Mikrotik 2.9.7 ?

Thanks

you need to configure rules like in following example:
http://www.mikrotik.com/docs/ros/2.8/howto/howto.content#12.2.6
do not forget to change syntax to 2.9 version.

P.S. src-nat rules place in srcnat chain, dst-nat ind chain=dstnat
