OPEN NAT Arris NVG589

[Deleted member 1560910]

I play mostly games on my pc and needed to get my nat to open. I read some threads and found were my model modem was I follow the instructions for which ports and when i wanted to run 2 different devices i got a pinhole conflict detected so i was like wtf. I am trying to have the nat open for my xbox one and pc . The only way i was able to get it to work on both was leaving the four entrys and restarting my xbox. I got my pc to open with going to IP passthrough and using the default sever allocation mode and manual entering my PC IP. Below are the details of what my modem IP said.So my question is doing it the way i did is it going to cause problems ?

Allocation Mode:
Off: The default server and IP Passthrough features are both disabled.
Default Server: Allows the device to forward all externally initiated IP traffic (TCP and UDP protocols only) to a default host on the LAN. You might need this if you cannot anticipate what port number or packet protocol an in-bound application might use. For example, some network games select arbitrary port numbers when a connection is opened. Or you might want all unsolicited traffic to go to a specific LAN host.
Passthrough: Allows the device's public IP address to be assigned to a single LAN client.
Default Server Internal Address: The IP Address of the device to receive the unexpected or unknown traffic.

Passthrough Mode: The method in which the WAN IP address will be assigned to the selected LAN client.
DHCPS-dynamic: The WAN IP address will be handed out by the device's DHCP server to the first LAN client that requests a DHCP lease. It may be helpful, after the device has obtained a WAN IP address, to cycle the desired LAN client's interface or reboot it. On disabling this feature, you should reboot the LAN client.
DHCPS-fixed: The WAN IP address will be handed out by the device's DHCP server to the LAN client whose MAC address has been specified. It may be helpful, after the device has obtained a WAN IP address, to cycle the LAN client's interface or reboot it. On disabling this feature, you should reboot the LAN client.
Manual: A LAN client must be manually configured with the device's assigned WAN IP address and gateway information.
Passthrough Fixed MAC Address: When Passthrough Mode is DHCPS-fixed, this is the MAC of the selected LAN client.

Passthrough DHCP Lease: When Passthrough Mode is DHCPS, this is the duration of the lease that will be handed out by the device to the LAN client.

You should be doing port forwarding, not pass-through. Pass-through allows ALL traffic to bypass NAT of your router and go to your PC, this is the equivalent of having a gate, but no fence surrounding the gate. Doesn't matter how strong you make the gate, when you can go right around it.

By having Open NAT you providing completely unfiltered access between your PC and the internet, that makes your PC "open season" for any hacker.

I switched it back. What about the xbox ?

What on the xbox requires an open port?
Xbox games should be establishing an outbound socket to the game servers.

Passthrough and port forwarding are not need to go out, they are need for unsolicited requests to come in.
You dont need it to play a game, or to browse the internet or anything like that, you need it only for when you are hosting a server/service that you want others to be able to connect to without your coimputer having to communicate with them first.
