: Configuring Xbox to work with multiple subnets
Microsoft & Community,

Has anyone been successful in implementing a fix to allow the Xbox to talk across multiple subnets?

We run mid-tier enterprise routing equipment and have our network separated into different subnets/vLANs for security and QoS purposes. The vLANs are broken into purpose-specific groups.

We can get most of the services to talk across the different vLANs in all desired use cases. Cellphones on the personal network can control tv's on the personal IoT network. But cellphones on the personal network cannot see or access printers or computers
on the business networks. We have even been able to get the SONOS system to connect; controllers that are on the personal vLAN can access the speakers that are on the personal IoT vLAN by implementing IGMP-PROXY service between the two vLANs. But, this has
not helped the Xbox situation.

We have
found a solution where someone was using NAT to change the IP addresses of devices in their personal vLAN to match the subnet of their IoT vLAN and get a connection to the Xbox; however this is not a solution that our system is capable of performing between
vLANs.

Can anyone with Microsoft or intimate knowledge of the firewall & security policies of the Xbox lend us some insight?

To help identify possible solutions here is the hardware we are running.

Hi Lucas_67-789,

Have you tried enabling IGMP Snooping on your VLAN config as it can help with multicast traffic. Also, Enable Multicast Enhancement (IGMPv3) on the SSID and turn on the mDNS service. You need to enable it only if you have multiple networks. By default multicast
is confined to one network. Also if you have Multicast and Broadcast Filtering enabled you need to add the Xbox MAC address to the Excepted Devices whitelist. Doing these things can sometimes help with media devices like Chrome casts and other media streaming
devices to work across subnets, so they may help with the XBox. As Xbox is primarily a home consumer product which most standard home users have flat networks there can sometimes be limitations as the developers don't really think about advanced networking
options built in by default. But, hopefully if these things were not set they may help you get it to work. Best of luck!

Tried that, did not work. It is not showing an IP address, subnet mask or gateway. I have the IP addy....

192.168.100.1

I need the subnet mask and gateway configurations.

Can you help with That?

It still did not work. i pressed the apple icon went to network settings then i clicked on wi-fi. it did not show me ip, subnet mask or gateway so i pressed advanced and it came up with another tab. i then clicked tcp/ip and i found IPv4 address, subnet
mask and router. IPv4 - 10.0.0.2 Subnet Mask - 255.255.255.0 Router - 10.0.0.1. so i manually put them into the xbox network configure option and it still said ip address error.

I've looked through everything and nothing has worked. When I go to Configure Network my IP Address, Subnet Mask, and Gateway are all 0.0.0.0 but when I manually but in the correct numbers it still doesn't work.

To make it even more strange under network configuration it detects IP address and Subnet mask but not gateway.
