Defylimits Posted July 6, 2023 Share Posted July 6, 2023 (edited) So I have 2 VMs I run constantly, my HAOS and a Windows 10 VM. They have both recently lost connection to my network, and it seems to be after I did an update 6.12.2. I do have VLANs running, a Server VLan (100) 10.10.10.0/24 and an IoT Vlan (20) 192.168.20.0/24. With both being on the 100 Vlan, and the HAOS having a second connection to the IoT VLan. The Unraid interface is on the 100 Vlan as well and is the default Vlan for the port the server is plugged into. I have tried updating the Network Source, from br0.100 to br0 and even virbr0 but no connection. Have also tried chaning the Network model to virtio-net from Virtio io but not luck then either. Weirdly I can access either of the IP's and the Window VM shows no connection, however in my Ubiquiti router I see all 3 connections and fixed IP's from the 2 VMs even after refreshing the MAC addresses from the Network connections as well. Am really confused, all the network connections for Dockers are working, some of which are host, others bridged and others on custom network. Not sure what the problem is or what to try, anyone have any idea? Diagnostics attached btw. tower-diagnostics-20230706-1638.zip Edited July 16, 2023 by Defylimits Quote Link to comment
Defylimits Posted July 7, 2023 Author Share Posted July 7, 2023 Ok bit of an update, I reverted to 6.12.1 but appears to have made no difference However I did notice my Windows VM can access docker webpages that are either on my custom docker network "dockernet" and dockers that are assigned to the "host", but not any of the dockers on br0, so there appears to be something blocking the VMs from communicating with the main network. So I'm going to guess its something to do with the routing table, but not sure how to fix that tbh. Quote Link to comment
Solution Defylimits Posted July 16, 2023 Author Solution Share Posted July 16, 2023 This Solution from Celsian worked - Thread - https://forums.unraid.net/topic/140858-vms-on-br0-cannot-access-the-internet-after-6120/#comment-1283343 On 7/5/2023 at 3:55 PM, Celsian said: Turns out the problem was actually with my network settings, when I restarted my unRAID server, the network connections stopped working again for both VM's. To resolve it I discovered that under network settings I had to enable bonding for eth0. I enabled bonding for the NIC, set the mode to backup and only included eth0 in the bond. After starting the VM's again, their network connections started working and the connections continued working after an unRAID restart. Quote Link to comment
Tucubanito07 Posted August 3, 2023 Share Posted August 3, 2023 Hello @Defylimits, did you ever figure out why in Unifi was coming up as multiple connections? What settings did you use in the network setting? Quote Link to comment
kristof Posted August 7, 2023 Share Posted August 7, 2023 (edited) This really helps me too. Thank You! I will not ask how you figured it out (?!?!?) I have the same network card as you: Asus XG-C100C 10Gbe Edited August 7, 2023 by kristof Quote Link to comment
