No matter what i do, ports will not forward

you have to TURN ON both FIREWALL AND NAT, and then configure the nat forwarding + firewall rule and then it will work

I can play online with with my xbox 360 with some friends but not others. I think it may be because of my nat.

Verify you have uPNP enabled on the router and that should do the trick.

Your router may not support it, so if not, you can setup a port fowarding rule for TCP port 3074 to forward to the IP address of your xbox 360

Port forwarding not working in ok firmware AGL6 or later

According to my very thorough testing some weeks ago, P-660-HW-D1 port forwarding is really very broken.

The worst thing is that not only does the port forwarding work properly, it lets packets to LAN addresses where they're not supposed to go. This means you're not safe behind LAN.

Firewalled or not, AGL.6 or AGL.7 shouldn't be used at all in my opinion, they're unsafe. When in routing mode, and having several LAN machines behind one Zyxel switch port (i.e. separate switch attached), I found that the port forwarding is completely broken.

I have contacted Zyxel Finland about this issue two weeks ago, and they initially thanked for the finding and said they're passing the issue onwards and investigate it.

The best current solution is to downgrade to (also very buggy) AGL.4.

Playing games vis LAN

For LAN play, you don't need to open any ports. However to forward ports you need to go to the routers control panel. Type the default gateway IP Address for your router in the address bar of your browser. If you don't know this, it can be found by opening the command prompt and typing "ip config". scroll down until you find Default Gateway and type the number (It will look like or very similar) Type that into the browser and it will ask you to log in. If you didnt set up the administrator login, just use the default password 1234. From there you should be able to find the port fowarding section, once you do just enter the range of ports you want to foward.

Unable to log into router to open ports

To log in to the router in order for you to do a port forwarding you can follow the steps from this link, but if the default username and password didn't work reset the router so it will be back to its default settings

Port forwarding

well to start, your connection would possibly be ADSL and your zyxel is set to provide DHCP address on your network, so its router capabilities could be turned on.

if this is true, you may need to rework the connection settings.

here's a recommendation:

1.set your modem to bridge mode (bridge only)
2.this will then be allowing your linksys to manage your DSL connection through PPPoE
3.after so, your linksys router should get a public IP address for an internet IP when you go to status tab (not an IP address starting with 192.168.1.xx)

after so, you may reconfigure your port-forwarding.

the reason why you will need to set your modem to "bridged" only is that if it is not, your zyxel's firewall is also turned on, provided that the linksys' firewall is always on. so even if you define which port will be opened on the router, it will still be blocked by the modem's firewall.
