Is it possible to setup port triggering on 881

Guys/Gals,

I have an xbox 360 and an xbox one both on my home network but they are never on at the same time, I know I can get a 1 to 1 nat but this will leave one of the devices with a strict nat. I currently have both Xboxes with moderate nat which is ok but I would like to get them both to an open nat state as I did when using my Buffalo router. On this router I had port triggering setup so this didn’t map to a static IP but would open and close natted ports as requested, is there a way of getting port triggering working on a Cisco 881? Currently I have CBAC outbound, an ACL inbound, no static nat translations and nat translation timeouts set. This works fine with everything else on my network.

 

interface Dialer1

ip access-group XBOXIN in

ip inspect XBOXCBAC out

 

ip inspect name XBOXCBAC udp timeout 30

ip inspect name XBOXCBAC tcp timeout 30

ip inspect name XBOXCBAC ftp

ip inspect name XBOXCBAC http timeout 30

ip inspect name XBOXCBAC https timeout 30

ip inspect name XBOXCBAC dns timeout 30

ip inspect name XBOXCBAC icmp

ip inspect name XBOXCBAC rcmd

ip inspect name XBOXCBAC realaudio

ip inspect name XBOXCBAC tftp

ip inspect name XBOXCBAC h323

 

ip access-list extended XBOXIN

 permit tcp any any eq telnet

 deny   ip any any log

 

ip nat translation port-timeout tcp 3074 30

ip nat translation port-timeout udp 3074 30

ip nat translation port-timeout udp 53 30

ip nat translation port-timeout tcp 53 30

ip nat translation port-timeout tcp 80 30

ip nat translation port-timeout udp 88 30

ip nat translation port-timeout udp 500 30

ip nat translation port-timeout udp 3544 30

ip nat translation port-timeout udp 4500 30

 

Any suggestions would be gratefully accepted and thanks in advance.

 

Cheers Dean
