Problem with connecting second network card

[Paloma Macetko]

Hello everyone

 

I have a strange problem.

 

I have a network cable connected to the onboard network card, with the following settings:
- IP: 192.168.20.200
- Gateway: 192.168.20.1
- Netmaps: /24

 

It's working perfectly.

 

However, I'm trying to install a 10 GB network card (Intel X540-t2), and when I install it, and go to configure it, I configure it (on port 1) to:
- IP: 10.0.0.10
- Gateway: [I left it empty]
- Netmaks: /24

 

And on port 2 I configured it to:
- IP: 11.0.0.10
- Gateway: [I left it empty]
- Netmaks: /24

 

However, when I restart Unraid, the Onboard network simply stops working, where Unraid has no connection to the network.

Config looks OK to me, but post the diagnostics.

Hi Jorge

 

I don't have access to the server right now.
But a question came to mind: could there be a problem with the network card that could affect the entire network?

I guess it's possible

You can't use 11.0.0.0/8 at all (or shouldn't, it's public/routable)

Not sure that's your problem but thought I'd note.

Do things work when only the onboard LAN is connected? I assume you're still trying to connect to the 192... address. Double check that it's using the same address (check your router).

Hello

 

If only the Onboard card is active, everything works perfectly.

I also tested via:
192.168.30.1

 

But it didn't work either.

Why would 192.168.30.1 work?

It works of the card is installed but network cable disconnected, but not when you connect cable to the new card? Based on what little info is shared I can't help but suspect this is on the network setup side, not unraid.
