Redirect local port traffic to remote host

i want to forward traffic originating from port 8103 of the ip pool 10.20.28.0/22 to a internal lan ip 10.20.28.1 port 7547 how can i achieve this?

Perhaps this??
add chain=dstnat action=dst-nat src-address=10.20.28.0/22 src-port=8103 dst-address=10.20.28.XX dst-port=7547

The rules I posted here: http://forum.mikrotik.com/t/dns-redirect-sanity-check/173965/1 might help for this.
