I want to disable Wifi on my ISP modem because it only supports password protection, no MAC filtering or anything, just password. So I want to have IPFire connect to the ISP modem through the Ethernet port and let IPFire manage the Wifi security. That’s easy.
But I also don’t want my desktop machine to connect to IPFire over Wifi. I want it to use Ethernet. IPFire is installed on a machine that has only one Ethernet port, so I am one Ethernet port short.
I have a very simple switch that I would like to use to work around that problem. I want to connect the ISP modem, IPFire and my desktop machine to the switch and make IPFire identify the ISP modem as the Internet connection (red) and my desktop box as a client in the green zone.
Is that possible? I’ve been trying for hours and it seems impossible. It seems that my PC can connect to IPFire, SSH to it or open the admin page on the browser, but IPFire can’t find the ISP modem through the switch so I have no Internet. It seems (I’m not really sure) that the modem is visible in ‘arp -n’ but can’t ping its address.
Thank you for any help.
