UDP Connection Limit Cisco Pix using static command

Hi there,

I am trying to limit UDP connections initiated from a higher level sec
int to a lower level sec int, aka my internal users to the internet.

I'm using static mapping as so:
static (inside,outside) x.24.110.26 192.168.1.110 netmask
255.255.255.255 50 10

Thing is I can't seem to get the UDP connection limit emphasized. I do
get the TCP limit working as it shows bellow but no luck for UDP.
I'm aware UDP is connectionless but the cisco docs for the static
command clearly says:
"Specifies the maximum number of simultaneous TCP and UDP connections
for the entire subnet"

Could anyone shed some light on this?

I appreciate it.
