Description

When connecting via PPPoE on a DSL connection, the IPv6 link-local address on an ISP's router may change periodically. This may occur with or without a drop in the PPPoE connection. Unfortunately, dpinger does not communicate with the new IPv6 link-local address at the ISP.

Disabling gateway monitoring action does not mitigate this issue. Disable gateway monitoring must be checked for IPv6 connectivity to be maintained in the event of an IPv6 link-local address change at the ISP's router.

Is this a dupe of #8136?

One is for DHCPv6, one is for PPPoE. They could be different problems, they could be the same problem, needs more research to tell.

I'm seeing this again in 2.4.4. Disabling gateway monitoring and gateway monitoring action in 2.4.2 100% resolved this issue. I was able to repeat by going back to 2.4.2.

I spoke with my ISP. It appears as part of a load balancing script on their end the PPPoE session will be dropped and redirected to another authentication server. During this process my static IPv4 and static IPv6 (global) stay the same. However, the IPv6 link-local address (ISP) will be different if the authentication server is different. As I said above, pfSense 2.4.2 used to handle this properly if I disabled gateway monitoring and gateway monitoring action.
