OPNsense Configuration

[guest44861]

Hello,

I come to you in one last hope regarding OPNSENSE configuration via Infomaniak's Public Cloud.

My target network:

Floating IP (public ip given by Infomaniak) ==> virtual router ==> WAN OPNsense -192.168.10.X (which is linked with the floating ip therefore internet access) ==> LAN OPNsense - 192.168.20.X

The WAN leg is managed in a network directly connected to the Internet. Everything works (ping 8.8.8.8 OK).
The LAN and WAN legs communicate well with each other.

However, the machines in the LAN network don't communicate with the Internet, or even with the gateway (which corresponds to the LAN leg, so they're in the same network!)
It seems that nothing is coming out.

Thank you for your help
Have a nice day,

If ping works and URL do not, then you probably have a DNS issue.

Since the WAN address is set from something upstream, it is probably also taking DNS server address from upstream. In this case, you probably need to have query forwarding checked and use the upstream DNS server.

ping works in OPNsense yes and my DNS is good after checking.

It's just that I have the impression that my machines in the LAN are not communicating with anyone.

Thanks
