How to check for CGNAT?
|
|
## Issue
|
|
|
|
All Firewall and Port forwarding rules are 100% correct, yet nobody can join your home-hosted Server!
|
|
|
|
If you have connection problems and you are using a Hosting-Service, contact them for assistance. If you want to use a VPS, take a look at this

# How to check for CGNAT?
|
|
|
|
## Method 1:
|
|
Open a command prompt, run ``tracert -4 beammp.com``. This will output a series of network hops. Wait for the operation to finish (may take up to 30 hops). Check the first few IP addresses after the IP of your Router/Modem/Gateway.
|
|
If multiple IP addresses within the range of ``100.64.x.x``-``100.127.x.x`` or ``10.xx.xx.xx`` appear after the first hop, you are most likely behind a CGNAT.
|
|
|
|
!!!note Note
|
|
|
|
The first hop will be your Router/Modem/Gateway and differs between Devices.
|
|
The official ranges for local networks are as follows: ``10.0.0.xxx`` - ``192.168.xxx.xxx`` - ```172.16.xxx.xxx``
|
|
|
|
## Method 2:
|
|
Find out the WAN IP on your router by looking it up on its interface. Compare it to the IP posted on e.g. https://whatsmyip.org . If they are NOT the same, you are behind a CGNAT.
|
|
|
|
## Method 3/Solution:
|
|
Call your Internet Service Provider for assistance.
|
|
Depending on your ISP, they might not offer dedicated *dynamic* IP adresses. Keep in mind, that a static IP is not necessary.
|
|
|
|
!!! warning "Warning"
|
|
|
|
Internet Service Providers may only offer dedicated IP addresses as a **pad option**.
|
|
Please check the prices of our partnered hosting services as they could be cheaper than this fee!
