24.7 Production Series / 6rd radvd and dhcpdv6 not starting after reboot
« on: October 18, 2024, 06:42:05 pm »
Unfortunately my ISP does not offer native IPv6. The best they offer is 6rd which is too bad.
Anyways I've been using opnsense since 24.7.1. I believe this issue has affected all dot releases since then. I still see this on 24.7.6.
If I reboot the opnsense box, radvd and the LAN's dhcp6 fail to load. There's not much special on my setup. I use manual outbound NAT for static port (have outbound for link-local & LAN networks). I also set the MTU of WAN to 1500. I think even disconnecting the WAN Ethernet for a moment then reconnecting can trigger this too.
I'll get messages like this:
Perhaps radvd/dhcpdv6 is being started too soon before 6rd is done? Just speculation
Last thing to note for now, if I restart the radvd & dhcpd6 services then IPv6 works as normal. Any reboot requires manually logging in to restart the services.
