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.
The first hop is your Router/Modem/Gateway and differs between Devices.
## 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, or as a paid option only. Keep in mind, that a static IP is not necessary.
