Beryl AX connected via ethernet to a TMobile 5G gateway.
Everything appears to be working, all wireless clients can access the internet. However, the LAN cannot access the internet. Wireless clients can access the server connected to the LAN port.
What am I missing here?
I did change the WAN port to LAN, but that caused the wireless clients to lose internet access, so I switched it back.
Hi,
Connect your laptop to the router's LAN port via a wired connection. Try to use ipconfig to check if your computer has obtained an IP address and can access the router's gateway.
If you can't access it, try clearing the router's configuration and restarting it.
Hello!
This issue is a classic case of Double NAT, which happens when both your T-Mobile 5G gateway and your Beryl AX router are trying to manage the network. Your wireless clients can access the internet because they are on the Beryl AX's network, which is routing traffic to the T-Mobile gateway. However, your LAN clients, such as your server, are having issues because their network is separate from the T-Mobile gateway's network. The best solution is to either set the T-Mobile gateway to bridge mode (if available) or configure your Beryl AX to function as a simple wireless access point, allowing the T-Mobile gateway to manage all network traffic and IP addresses.
So the LAN interface isn't being routed. That makes sense.
All of the networks on the beryl (LAN & WLAN) are all configured for the same (private 10.x.x.x) IP network with DHCP handing out IP addrs within a subset of the network. The DHCP IP addr assigned by the TMobile is 192.168.x.x. Being in the same network is why the wireless clients can access the LAN port.
I should have mentioned that I am traveling and the TMobile 5g devices does not belong to me. I don't have access to it's configuration.
I guess I could try connecting in repeater mode, or, as suggested, just configure the beryl as an AP.
Thanks for the tips, you've given me a couple of options to try.
