Automatic WAN interface reset upon connection drop?

[andrew_241]

I'm using an AT&T residential gateway in passthrough and am using a DHCPv6 client configuration file override to get a few IPv6 prefix delegations. Since AT&T's gateway device clears all prefix delegations when it is rebooted, I lose IPv6 connectivity until I do a manual reset of the WAN interface in the OPNsense GUI, either by disabling and reenabling the WAN interface, or by doing a quick 'Save' and 'Apply changes'. IPv6 is restored, because the configuration file is reloaded, and OPNsense re-requests the delegations.

Is there any way to have this process happen automatically when OPNsense sees that the WAN connection is dropped and reestablished?

Thanks!
