Help with 1:1 mapping using NAT

I’m trying to setup a relatively simple test but I’m running into problems.

I have 2 interfaces, Local and Public setup plus the following:

/ip firewall nat add chain=dstnat dst-address=192.168.1.1-192.168.1.254 action=netmap to-addresses=192.168.10.1-192.168.10.254
/ip firewall nat add chain=srcnat src-address=192.168.10.1-192.168.10.254 action=netmap to-addresses=192.168.1.1-192.168.1.254

I’m trying to get the 192.168.10.0/24 subnet to have a 1:1 mapping
to 192.168.1.0/24 subnet. My test station is using 192.168.10.75 with
a gateway of 192.168.10.1, but it is unable to ping anything on the
192.168.1.0/24 subnet. 192.168.10.0/24 being local, and 1.0/24 public.

Ultimately what I need to do is setup a configuration where 5 subnets
(all the ip’s being static) are transparently moved to 5 new subnets,-
since we’re changing uplink providers and getting new ranges …

Hope someone can tell me where I’m making a mistake.
2.9.8 is the version of mikrotik software.

Thanks
