Topic : VPS loses IPv6 default route

Posted By: ppconsulting on January 24, 2022, 2:22 pm

Hello,
Every couple of weeks it appears that some of my KVM VPS's running on Virtualizor lose their IPv6 default route and require a manual re-add within the virtualized OS. This appears to happen on VPS's running on Ubuntu 18.04/20.04 a majority of the time, and has been occurring off and on for the past 6 months.
An example of the routes shown after IPv6 loses connectivity is below:

Code
root@canadainc01:~# ip -6 route

2602:fcd3:10:129b::/64 dev eth0 proto kernel metric 256 pref medium

fe80::/64 dev eth0 proto kernel metric 256 pref medium

When it loses connectivity, there is no default route which should be directed at 2602:fcd3:10::1.
Has anyone else had this happen to them, and is there a known fix for this?

Hi,

Have you enabled 'use routed option' in Ip pool on panel ?

Hello jevingala,
I'm not sure whether this is required as I didn't have this issue when I first starting using Virtualizor with these same settings. I'm also the one that controls the routing on this network using a separate device as a router and have made no changes to cause this.
