22.7 Legacy Series / IPv6 Issues with 22.7_4
« on: August 15, 2022, 02:33:10 pm »
After three years of pretty much flawless operation I encountered an issue I'm not able to solve myself.
Since my upgrade to 22.7 I keep losing IPv6, intermittently.
Service is dslite, upon release/reload of the interface, manually restarting dhcpd6, IPv6 is working fine, but after a while it stops
start:

It's a multi-wan setup with dpinger for gateway monitoring.
This behavior is really strange. Any pointers or assistance would be most appreciated.
