I want to have the outside interface accept specific port traffic and forward to inside host.  The corrent configuration looks like this.

so what i want to do is have outside (123.33.33.68) map to 10.0.7.2 all traffic ports 25000-25010

>static (inside,outside) 123.33.33.68 10.0.7.2 netmask 255.255.255.255 0 0              
That one line takes care of the nat for all ports.
Now you just need to create an access-line entry:

  access-list 1 permit tcp any host 123.33.33.68 range 25000-25010

Then re-apply the access-list to the interface (required step when changing the acl)

  access-group 1 in interface outside

OK.. when I enter the following from the config t


  access-list 1 permit tcp any host 123.33.33.68 range 25000-25010

i get  a error.

I did not enter the static (inside, outside) as it's in the config I started with the access-list 1 first

My bad. No "-" in the port range. Use a space instead:

    access-list 1 permit tcp any host 123.33.33.68 range 25000 25010
                                                                                        ^^

If you want both, then two lines:

   access-list 1 permit tcp any host 123.33.33.68 range 25000 25010
   access-list 1 permit udp any host 123.33.33.68 range 25000 25010
