Re: NATing Port Range - IOS

try using destination/rotary nat, even though its well known that it
works for only TCP, you should test in on newer codes, never know it
may work.

#ip nat pool LOCAL x.x.x.x x.x.x.x type rotary
#ip access-l ex INTERNET-TO-INSIDE
   perm udp any host <z.z.z.z> range 10000 20000
# ip nat inside destination INTERNET-TO-INSIDE pool LOCAL

Test it and let us know.

Swap
#19804x2
