Ok, I have the PIX 501 up and running (thanks to Barty Boy) New problem. This replaced the Linksys Wireless router AP we were using. Well now with the Pix in and up, the family is experiencing problems with their X-Box 360. Their are a few port forwards that need to be added, however I have no clue the format or how to do it bi-directional. 2 UDP Ports and one TCP port.

Unless you have an access list applied to the inside interface, you should not have to worry about opening up any ports outbound to the Internet from the inside.  This should be implicitly allowed already.  However, look for the following command (or something similar) in your PIX config:

access-group inside_access_out in interface inside

If you see an "access-group" command with the last word referencing the "inside" interface, then you have an ACL applied to the inside interface that will need to allow the ports outbound.

As for allowing ports inbound from the Internet, you should have an access list already applied to the outside interface and it will be listed in a similar access-group command referencing the "outside" interface.  Let's say the name of the ACL is "outside_access_in".  Here is the syntax for opening up a port from the outside:

static (inside,outside) tcp interface 80 192.168.1.1 80 netmask 255.255.255.255
access-list outside_access_in permit tcp any interface outside eq 80

The first command configured port forwarding of TCP 80 (www) from the PIX public interface IP address inbound to host 192.168.1.1 on the internal network.  The second command ALLOWS the traffic on TCP 80 to flow inbound to that public IP address (the interface of the PIX itself).  It's not enough to just have one of those commands or the other, you have to have both.  So, for your example of 2 UDP ports and one TCP port, here is a template of what you should have:

static (inside,outside) udp interface <UDP_port_1> 192.168.1.1 <UDP_port_1> netmask 255.255.255.255
static (inside,outside) udp interface <UDP_port_2> 192.168.1.1 <UDP_port_2> netmask 255.255.255.255
static (inside,outside) tcp interface <TCP_port_1> 192.168.1.1 <TCP_port_1> netmask 255.255.255.255
access-list outside_access_in permit udp any interface outside eq <UDP_port_1>
access-list outside_access_in permit udp any interface outside eq <UDP_port_2>
access-list outside_access_in permit tcp any interface outside eq <TCP_port_1>

The first 3 static commands implements port forwarding for the 2 UDP ports and 1 TCP port (substitute the ones you need) and the last 3 access list statements allows those three ports inbound to host 192.168.1.1 on the inside.  This internal IP address should be the Ip address of your X-Box.

Hope this helps...
