IP Conflict
Posted: Thu Mar 18, 2021 3:55 pm
I have recently installed a new router running pfSense. I'm seeing an issue in the router's system
So from the device running Alpine Linux, this is part of the startup.sh
It does nothing for the IPv6 side which thinks it has two devices..
Using SSH I can get to the same device. Below is the ifconfig results
172.25.25.210 & 172.25.25.241
Is there a way to set the IPv6 to also have an alias?
Should I disable IPv6 on the device? Is that a bad thing?
