h323 port translation on PIX515

[aliggee]

I'm new to cisco pix's and cisco to be honest.
Trying to route calls from my as5300 to 1 destination via the pix515.

as5300
------
fastethernet0 is 192.168.0.44 255.255.255.0
default route to 192.168.0.33 255.255.255.0

pix
----
fastethernet1 inside is 192.168.0.33 255.255.255.0
fastethernet0 outside is 216.38.22.203 255.255.255.248
default route is 216.38.22.206 (isp router address)

How do i set configure the pix to take calls in on 1720 from the as5300 and send them out on a different port number?

Grately appreciate any help with this.
Regards
Alistair.

static (inside, Outside) tcp interface 1720 192.168.x.x 1735 netmask 255.255.255.255

Basically this will redirect incoming packets destined for the outside interface on port 1720 to port 1735 on the internal address of 192.168.x.x.
