Nat mapping? (a.k.a. port forwarding)

[pirateclem]

I have a situation which is new to me need some assistance. I have a pix 515 and a vendor who needs to put an appliance in my network. This appliance needs to receive and send data back to the vendors network but also mount a SAMABA share in my network. So best I can determine is:

Vendors network -> Routable IP on my side -> PIX -> Internal IP in my network -> Appliance

So, how do I go about setting up the PIX to know that if something hits it for IP 100.100.100.100 port 8180 that it should forward to internal IP 10.1.1.1 port 8180?

static (inside,outside) tcp interface 8180 10.1.1.1 8180 netmask 255.255.255.255 0 0
