Installed New nic, not accepting old ip

[Quiltface]

I am running freenas 9.10
I just put in a new intel dual port nic, i went into the console and deleted the old interface and setup the new one with the old IP. Now I can only ping the server with the old nic plugged into the switch...

I am not sure why this is happening am I missing some sort of non obvious step when setting up a new nic.

If i give the nic a new IP i can ping that fine but it seems as the system is caching that IP to that old nic.

Let me know what you need to help me troubleshoot this. I am currently trying to get net connectivity back on this and currently only have console.

Ok so bge0 was the old one which isnt showing up anymore so thats good... but i only need em0 and only .253.

currently the only way i can ping any of these IPs is if i have both ports connected to the switch... and I just got finished resetting all the nic settings in the console so I am not sure why these nics have these settings.

Actually in mid typing this... I unplugged the nic i didnt want to see if it would work and it dropped pings... i plugged it back in and i am still losing pings.

i can ping .125 and .126 but not .253 which is what my webui is.

Try using a new ip for the new NIC. Or you can reboot your router/switch. You have a IP conflict because you have 2 Mac addresses using the same ip in your ARP table.

yeah i thought about that... i can get new IPs configured but i cant get them to be accessible by the webui.

im going to reboot my switch again, shutoff my server and unplug all the cables... and try again

how can i get rid of the .125 and .126

I think I got it...

This is what I did... consolidated as much as i can.

• Deleted interfaces
• unplugged ethernet cables
• i didnt have to do this because my arp cache was clear already but clear the arp cache on the freenas server
• shut down freenas
• rebooted switch (i have a dumb switch)
• deleted any address leases in my DHCP server for the Freenas server
• cleared arp cache on my dhcp server (or at least for anything pertaining to freenas)
• cleared arp cache on my dns server (or at least for anything pertaining to freenas... doubt this is necessary but what the hell)
• rebooted my firewall (doubt this is necessary either... my firewall is not doing my dhcp)
• booted up my freenas
• configured my NIC

Im going to do a few more test but i think this is it... arp can be a sob sometimes.
I would have issues where it was pinging just fine and then i plug in another nic and it wouldnt work anymore... then i would unplug the nic i just plugged in and it still wouldnt work.
Or it would be working and then i would reset em1 which wasnt plugged in or configured (it had that dhcp address i was trying to get rid of) and after i reset the nic em0 stopped responding to pings...


going to do a bit more testing to see if i come across any other nuances.

Glad to see you got it fixed.
