Ubuntu Server upnp?

[the_mulletator]

I have a home network set up as follows:
Internet <--> Ubuntu Server <--> Router <--> Computers & XBOX

Everything works great on the computers but the XBOX can't connect to XBOX live. It says my NAT is moderate and it needs to be open. I searched on Google and found several sites on the subject. The most relevant one that I found was published in 2006 and it said I need upnp on my server to use XBOX live properly. Does anyone know how to get the XBOX live working on my server?

why are you using a ubuntu server between router and internet? cant you connect straight from the router to internet.

Internet <--> Router <---> Switch <---> Computers & XBOX.

Simpler the above way. Enable upnp on the router (most routers support this these days) and you should be good to go.

I'm using the server for a web based torrent client as well as a file server and a squid proxy server.

XBOX live works fine if I remove the server.

Of course XBOX will work. Forcing the Ubuntu to filter traffic is going to be difficult.

UPNP is nothing but a simple port forwarding mechanism - only that it requires no manual input from the user. The App that requests UPNP will automatically configure rules on the gateway device that supports UPNP.

Check what is exactly required by the XBOX and manually forward it by Squid.

I found this on a post at another forum:

 
   $IPTABLES -t nat -A PREROUTING -i $WAN_IF -p tcp --dport 3074 -j DNAT --to-destination $XBOX_IP
   $IPTABLES -t nat -A PREROUTING -i $WAN_IF -p udp -m multiport --dports 88,3074 -j DNAT --to-destination $XBOX_IP
   $IPTABLES -A FORWARD -i $WAN_IF -d $XBOX_IP -p tcp --dport 3074 -j ACCEPT
   $IPTABLES -A FORWARD -i $WAN_IF -d $XBOX_IP -p udp -m multiport --dports 88,3074 -j ACCEPT

The guy on that forum was trying to share a conection with a desktop PC running ubuntu and a wireless connection. Like this:
Wireless <--> Desktop <--> XBOX

He had it all set up but had the same NAT problem and he said that these mods to his iptables fixed it in his application.

I don't really understand the $WAN_IF part. If I fill in my XBOX IP and whatever should go in the $WAN_IF spot will it work? I disabled squid for now to simplify things.

You do not need upnp to get xbox to work. UPNP actually should be disabled. It is seriousl the worst idea, EVER, with respect to networking security.

Google "xbox live tcp udp ports" and you should quickly figoure out which ports to open.

That's a script. Anything that begins with $ is a symbolic reference. I grabbed that post from:
Connecting to XBox Live through a linux computer connected to a wireless LAN.

$IPTABLES will be either be iptables or squid equivalent. $WAN_IF is the wan interface of the squid server. $XBOX_IP will be the IP of XBOX.

So for e.g. this command:

$IPTABLES -A FORWARD -i $WAN_IF -d $XBOX_IP -p udp -m multiport --dports 88,3074 -j ACCEPT

is actually:

iptables -A FORWARD -i eth0 -d 192.168.1.50 -p udp -m multiport --dports 88,3074 -j ACCEPT

where "iptables" is the command; eth0 is the interface of the squid server connected to the internet-router; and 192.168.1.50 is the IP of the XBOX.
