Have System Requirements Increased?

No, this default predates the fork even.

No idea why then that on 24.7.12 (and prior versions that I have used) this gateway IPv6 Configuration Type stayed set as None, but the update to 25.1 definitely switched it to DHCPv6 which then caused my problems.

It's possible that when I first joined OPNsense at version 24.1.x I may have manually set the gateway IPv6 Configuration Type to None during my initial set up, but all upgrades after that point did not set it back to DHCPv6, but the 25.1 upgrade definitely did

Are you using PPPoE?

[jim1985]

Yes, I am

[franco]

Ok, easy then:

community/25.1/25.1:o interfaces: remove "Use IPv4 connectivity" setting as it will be set by default

We've removed the Use IPv4 connectivity setting because it was backwards for PPPoE (it should be set by default but it was unset). Removing the setting allowed us to force the new (and correct default), but it also means that your PPPoE was now looking for IPv6 connectivity.

Old bug, good progress, but also sorry for the noise.

Ah ha. Yes that makes sense.


Will there be a way that you can stop it looking for IPv6, maybe after a short timeout, if it's not available?

Probably not. Then it would stop trying for legitimate ipv6 setups that have a temporary failure.

Fair point.

Well I'm not too fussed, now I was able to locate the source of my problem & put it right anyway

Thank you! I've been having spontaneous reboots of the home internet for two days driving everyone crazy -- and this was the answer! I shutoff Ipv6 on WAN and LAN and my memory usage plummeted from 98% to 13%.

In the interest of marking this as solved, I finally got to the bottom of the cause of the problem.


It seems that the upgrade had enabled something to do with IPv6 on the gateway. I only have IPv4 available to me so changing the following has completely fixed this problem for me:


Interfaces -- [WAN] -- IPv6 Configuration Type: None



It had set itself to IPv6 Configuration Type: DHCPv6


This was somehow causing the system to consume all of it's available RAM and the system load was going crazy high until eventually the system and my whole network became unusable. Presumably it was attempting over and over again to obtain a DHCPv6 address which it was never going to get as DHCPv6 is unavailable to me
