[SOLVED] adding 10g nic on different subnet kills internet

[dkersten]

With only the 1 gig nic enabled and plugged into my network, everything works fine.  However, I also have a 10 gig nic that I use to connect directly to my main windows pc to transfer new rips to the UnRaid share.  This second nic is on a totally different subnet that has no connection to the rest of the network (no DNS server, no gateway).  I can enable the 10g nic and transfer files from my PC to the UnRaid share at 950+ MB/s, just like it should.  But as soon as I turn on the port on the 10g nic, Unraid loses internet.

 

From what I can tell, it is trying to use the second nic to connect to the internet, even though it is set as eth1, and the 1 gig nic that is actually connected to the internet is set to eth0.  

 

Can anyone help me figure out how to configure this to ignore the eth1 10gbe nic when it comes to downloading things from the internet?  Attached is my ethernet settings page.  I am running 6.8.3 and it is fairly clean (installed yesterday). 

 

Edit to add:  I have searched for a solution and found multiple articles on how to use the 10g card as a passthrough for my PC but I have no desire to do that here, I just want to connect my PC to the UnRaid share through the 10gbe nic, the PC has it's own 1gb nic connected to the main network (192.168.1.*) and that configuration gives me the least issues (at least it did when my storage server was windows based and not unraid).

Does it make a difference if you leave the default gateway for eth 1 blank?

It appears to be working after removing the gateway from eth1.  Thanks!

No problem, going to mark this solved if you don't mind.
