Hi list users, I am not a network administrator and know only a little bit about the topic. I need to set up a switch in my lab, so that I can have a wifi access point and an SL7 desktop computer on the same network, as I need to be able to connect to the pc using a tablet. My administrator does not allow switches to be on the network, so I need two network adapters on my desktop, one for internet, and on on the local switch.
I tried a nominal setup at home first, with my home wifi access point, router/switch and using only a single adapter. I managed to open the required ports using firewalld, and my setup works great at home, where I can connect a tablet over wifi and access my desktop as I need. The only problem I see there is that the ports I opened are open to the world, but since that was temporary for testing, it was fine. They are now closed. I bought a usb ethernet adapter, which shows up as a network interface on my lab computer. I now need to configure my lab computer as follows. I would like the onboard network adapter to be the default (used for web browsing etc), and use default settings (public zone, etc). And I would like the new usb network adapter to have the required ports open, so that I can access that computer over wifi with my local switch. As I said, I have used firewall-cmd to open and close ports. I know a little bit, but not enough to accomplish what I describe above. Can anyone help with this? Just let me know if more information is needed. Thanks, Chris
