1:1 mapping format changed?

I am preparing a changeover for my network into one with public IP’s for clients. I am preparing a rb1000 as the new main gateway.
I try to use the example from the ROS ref. manual but input from that example (same as Wiki) is not accepted by my router.

Manual is v.3 while Wiki I don’t know. But I try to install in a v5.beta system.
Instead of the mentioned IP range like 1.1.1.1.1-1.1.1.254 in at least one of the options (Src.Address/Dst.Address AND the action ´netmap´ ToAddresses) this noticion is not accepted. I have to use the /24 notificacion?
In itself I see no problem in it but since the manual don’t use it while obviouse if it could I now have my doubts.

So, is this a bug, is it a problem? Will netmap still work and are clients always mapped into same IP?

I cannot test it since I have no public address range yet.

I am going to follow this one too. I used this heavily in 2.9 and it worked fine, however in 3.x and 4.x it seems like I can’t do it the same way. Now I was doing something different where I had 1 incoming connection being src-natted using netmap, each next connection got the next IP in line. This doesnt work the same anymore.
