No WAN access after second NIC installed

[SuperG]

I am unable to get Unraid to access the internet after I installed a second NIC. 

LAN works fine as far a connectivity to and from the server but I am unable to ping internet sites or access any of my docker 'programs' from outside the network.

 

Routing table issue? I cannot figure this out, any help is greatly appreciated.

You use manual setting and eth1 in linkdown, btw nothing abnormal ( although eth1 config. in same subnet with eth0 ). Pls provide below test result

 

ping 192.168.1.1

ping 8.8.8.8

traceroute 8.8.8.8

dig google.com

destination host not reachable for all of those. 

 

I have a backup from yesterday that I am going to restore from. Sorry if I wasted your time.

Anyway, if IP correct, it look like not Unraid issue.

Well I restored from backup without changing any router settings so it was totally a software unraid issue

Pls check does eth1 still setting as previous, as mention, eth1 shouldn't setting same subnet as eth0.

Suppose remove gateway at eth1 could fix the problem.

 

IPADDR[1]="192.168.1.175"
NETMASK[1]="255.255.255.0"
GATEWAY[1]="192.168.1.1"

 

What eth1 use for ?

I think I understand what you are saying now. Both ethernet connections were on the same subnet.

 

My original goal was to have my virtual machine run on the secondary NIC. This NIC card and VM were on the same subnet. Somewhere along the way I think the secondary NIC started acting as the primary for unraid.

 

I couldn't have the server down to try and figure out the solution. So I uninstalled the NIC and restored from the backup. But I promise you I didn't do anything to the router or any other network configuration outside of the unraid software.

 

I'm not sure what the correct installation is for adding a secondary NIC card. I'll do some research on the forums and look around.
